# Office & Paper Fasteners

Staples are bought to fit a stapler: the size code (26/6, 24/6, 23/x, No. 10) must match, and leg length sets how many sheets one staple holds. Clips are bought by jaw capacity, not by the name small or large. For papers kept for years, plain steel rusts and rubber bands rot, so material matters more than grip.

## How it works

Office fasteners hold paper in one of three ways. A staple pierces: the stapler drives two wire legs through the stack and an anvil bends them flat underneath, so the legs must be longer than the stack is thick, and the wire and crown must fit the stapler's channel. A clip clamps: a paper clip grips by the twist and spring of its wire, and a binder clip by a folded strip of spring steel, so what matters is how wide the jaws open. A rubber band wraps and holds by tension; its size number encodes its width and flat length. All three age. Zinc-plated steel rusts and stains paper, rubber hardens and sticks, and some plastics break down, which is why archivists take them off records that are rusting or going into permanent storage. [5] [6] [7] [31] [1]

| Family | What it is | Suits |
|---|---|---|
| Pierce and clinch | Staples, brass paper fasteners and prong fasteners go through the paper and stay. | Reports and packets that should not come apart. |
| Clamp | Paper clips and binder clips squeeze the stack and come off without holes. | Papers that will be separated, copied or scanned. |
| Wrap | Rubber bands hold a bundle by tension. | Bundles of files, envelopes or cards, short term. |

1. **Fastener type.** Staples, paper clips, binder clips, or rubber bands?
   The types do not substitute: staples need a matching stapler, clips come off, bands wrap. Each answer leaves one product family and its own fit facets. The query usually names the type already.
   If staples: ask Staple size code, Strip format; skip Binder clip capacity, Paper clip size, Rubber band width, Rubber band flat length, Latex-free.
   If binder clips: ask Binder clip capacity; skip Staple size code, Staple leg length, Strip format, Wire grade, Paper clip size, Rubber band width, Rubber band flat length, Latex-free.
   If paper clips: ask Paper clip size; skip Staple size code, Staple leg length, Strip format, Wire grade, Binder clip capacity, Rubber band width, Rubber band flat length, Latex-free.
   If rubber bands: ask Rubber band width, Rubber band flat length, Latex-free; skip Staple size code, Staple leg length, Strip format, Wire grade, Binder clip capacity, Paper clip size, Sheets held.
   Skip if already known: product type named in the query, an earlier answer naming the type.

2. **Staple size code.** Standard 26/6, long-leg 24/8, heavy-duty 23, mini, or cartridge?
   Staples only work in staplers built for their code, so this removes every other size. Standard maps to 26/6 or 24/6, long-leg to 24/8 or 26/8, heavy-duty to both heavy-duty values, mini to No. 10, cartridge to sealed cartridge.
   If 23/x heavy duty or US heavy duty (gauge unstated): ask Staple leg length.
   If 26/6 or 24/6 (standard): ask Wire grade, Strip format; skip Staple leg length.
   Skip if already known: stapler model, size printed on the old staple box.

3. **Sheets held.** How many sheets: up to 30, 70, 120, or more?
   Sheet count picks the leg length for staples and the jaw capacity for binder clips. Answers map to the four bands in order. A standard 26/6 or 24/6 answer with 70 or more sheets is a mismatch needing heavy-duty staples.
   If up to 30 sheets: skip Staple leg length.
   If 70 to 120 sheets or over 120 sheets: ask Staple leg length, Binder clip capacity.
   Skip if already known: stapler's rated sheet capacity, an earlier answer about document size.

4. **Material.** Filing these papers for years, or just for now?
   For years maps to stainless steel first, then plastic or plastic-coated; for now sets no material filter. Stainless fasteners are uncommon, so a for-years answer removes most of the range.
   Skip if already known: archive, records or family-papers context stated earlier.

## What to surface

### Fastener type

Which kind of fastener this is: staples, paper clips, binder clips, rubber bands, brass paper fasteners or prong fasteners. Each type holds paper differently and has its own fit rule, so the type decides which other facets matter. Staples must match a stapler. Binder clips are used in place of paper clips for large stacks and leave the paper intact. Rubber bands are for bundles, not records you keep. [7] [6] [27] [28] [29]

Values: staples, paper clips, binder clips, rubber bands, brass paper fasteners, prong fasteners.
Question to ask: Staples, paper clips, binder clips, or rubber bands?

Used as: top-level split, filter. Data: on the listing, backfill cost none. Look for it as: The product noun in the title: 'Standard Staples', 'Binder Clips', '#33 Rubber Bands'.

### Sheets held

How many sheets of ordinary office paper (80 gsm or 20 lb) the fastener is rated to hold, grouped into four bands. This is the number brands rate staples on, and it moves with leg length: Swingline rates 1/4 in at 25 sheets, 1/2 in at 90 and 15/16 in at 210; Rapid rates 6 mm at 20 to 30 and 15 mm at 80 to 120. The stapler moves it too: Swingline's 1/4 in Optima staple holds 25 sheets in a standard stapler and 40 in a flat-clinch one. Standard 6 mm staples stop near 30 sheets. [9] [10] [13] [16] [17] [22] [24] [30]

Values: up to 30 sheets, 30 to 70 sheets, 70 to 120 sheets, over 120 sheets.
Question to ask: How many sheets: up to 30, 70, 120, or more?

Used as: top-level split, filter, sortable. Data: derived from listing fields, backfill cost low. Look for it as: Brand spec tables only: Swingline 'Sheet Capacity (20 lb paper)', Rapid 'For stapling up to 20 sheets (80 gsm)'. Retail staple titles carry no sheet rating.
Assign the band from leg length using the brand scale. For binder clips, compare the stack_thickness_mm of the band with clip_capacity_in.
Chart: Leg length to sheets scale.

### Material

What the fastener is made of, which decides whether it will rust, harden or break down on stored paper. Ordinary staples and clips are zinc-plated steel, and the National Archives (NARA) shows a rusting paper clip staining a record. For papers kept long term, NARA uses stainless steel clips over a folded paper strip, and stainless staples on strong paper. Two university archives prefer plastic clips. NARA also warns that office plastics degrade, and that rubber bands harden, break and stick. [1] [3] [4] [5] [7] [27] [18] [2]

Values: zinc-plated steel, stainless steel, plastic or plastic-coated, black-oxide or painted spring steel, brass, natural rubber, synthetic rubber.
Question to ask: Filing these papers for years, or just for now?

Used as: top-level split, filter, shown on the card. Data: needs research, backfill cost low. Look for it as: Titles say 'Stainless Steel', 'Vinyl-Coated' or 'Non-Latex' when it is a selling point. Rapid pages say 'Galvanised'. Plain listings say nothing.
Default unstated metal staples and paper clips to zinc-plated steel, and unstated binder clips to black-oxide or painted spring steel (Wikipedia; Quill's binder clip guide). Search the title and bullets for stainless, AISI 304, vinyl, plastic, EPDM and non-latex.

### Staple size code

The code that says which staplers a staple fits, written as wire number over leg length in millimetres, such as 26/6, or as a name such as No. 10. A staple of the wrong code jams or will not load, so this is a hard fit filter. Most desk staplers take both 26/6 and 24/6; Rapid lists both on its standard staplers. Rapid sells 23/x as heavy-duty staples, and Swingline sells its heavy-duty strips for heavy-duty staplers only, but US titles say 'heavy duty' without a gauge, so the register keeps that as its own value. [5] [24] [21] [15] [14] [8] [30]

Values: 26/6 or 24/6 (standard), 24/8 or 26/8 (long leg), 23/x heavy duty, US heavy duty (gauge unstated), No. 10 (mini), brand-specific strip, sealed cartridge.
Question to ask: Standard 26/6, long-leg 24/8, heavy-duty 23, mini, or cartridge?

Used as: top-level split, filter. Data: derived from listing fields, backfill cost medium. Look for it as: European titles carry the code (Rapid 'Standard Staples 24/6'). US titles carry no code: 'Quill Brand Standard Staples, 1/4" Leg Length' or 'Standard Heavy Duty Staples'.
Map US 'standard 1/4 in, 210 per strip' to the standard value and US 'heavy duty' to US heavy duty, not to 23/x, since no source gives the US gauge. Cartridge titles do not name the stapler ('Standard Staple Cartridge, 5,000 Staple Count'), so read the fit from the brand page, top N first.

### Paper clip size

The size name on a wire paper clip: #1, #2, standard or small, or jumbo. Paper clips hold a moderate number of sheets, and the size name is how listings sort them, but the names are not one scale: JAM sells the same clip as 'Standard Paper Clips, Small'. No source read gives #1 or #2 dimensions, so the names are not ordered here. Above a thin stack, a binder clip is the usual swap. Listings also split smooth from non-skid finishes. [28] [6] [7]

Values: #1, #2, standard or small (no number), jumbo.
Question to ask: Regular paper clips, or jumbo?

Used as: filter, shown on the card. Data: on the listing, backfill cost none. Look for it as: In the title: 'Gem Paper Clips, #1', 'Paper Clips, #2', 'Smooth Standard Paper Clips', 'Small Paper Clips', 'Jumbo Paper Clips, Nonskid'.
Regular means every value except jumbo. Map 'Standard' and 'Small' titles to the standard-or-small value; do not convert them to #1, since no source ties the names to numbers.

### Latex-free

Whether a rubber band is made without natural rubber latex, for example from EPDM synthetic rubber. Natural rubber latex is in ordinary rubber bands, and the allergy bodies AAAAI and ACAAI tell people with latex allergy to avoid direct contact with latex products, since reactions can be severe. Non-latex bands say so in the title, and a title that does not say so should be treated as latex. Alliance also claims its EPDM bands resist heat, ozone and age better. [35] [36] [34] [32] [29]

Question to ask: Anyone handling them allergic to latex?

Used as: filter. Data: on the listing, backfill cost none. Look for it as: 'Non-Latex' appears in the title only when true, as in 'Alliance X-Treme EPDM ... Non-Latex'.
A band title without 'Non-Latex' or 'EPDM' counts as may contain latex, never as latex-free: AAAAI names rubber bands among latex products, and Blue Summit says most bands are natural rubber.

### Binder clip capacity

How thick a stack a binder clip's jaws can take, in inches. Capacity, not the size name, is the number to filter on, because the names do not agree: Quill's large 2 in clip takes 1 in, JAM Paper's large takes 3/4 in, and Quill's own buying guide says large clips take up to 1.25 in. Quill and JAM titles put the medium clip at 5/8 in, while the same guide says 0.645 in. [27]

Range: Quill titles: mini 1/4 in, small 3/8 in, medium 5/8 in, large 1 in. JAM: small 3/8 in, medium 5/8 in, large 3/4 in.

Used as: filter, sortable. Data: needs research, backfill cost medium. Look for it as: In some titles as '5/8" Capacity' next to the width, for example 'Medium 1-1/4" Wide Binder Clips, 5/8" Capacity'. 9 of 22 binder clip titles on Quill state it.
Most titles give only a size name or width. Read capacity from the brand's product page, top N first. Only the medium 1-1/4 in wide to 5/8 in pairing (Quill, JAM) is safe to infer; flag any other inferred value.
Chart: bar length for capacity, with the stack band from stack_sheets drawn behind.

### Rubber band width

The cut width of the band strip, in inches, which sets how hard it grips. Width sets grip: Rubber Band King gives 1/16 in for light bundles, 1/8 in for heavier ones and 1/4 in for rough handling, and wider bands resist snapping. The size number encodes width and length, but not cleanly: most 1/16 in bands are #8 to #19, yet #117B is 1/8 in, and the charts disagree on #107 (Alliance and Quill 5/8 in, Rubber Band King 1/8 in). Read width from the title. [31] [33] [34] [29] [32]

Values: 1/16 in, 1/8 in, 1/4 in, 3/8 in or wider.
Question to ask: Light bundles, heavier ones, or rough handling?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: In the title as the size number plus dimensions: '#33 Rubber Bands, 3-1/2" x 1/8"'.
Light maps to 1/16 in, heavier to 1/8 in, rough handling to 1/4 in or wider. When the title gives only the size number, look the width up in the Alliance chart.
Chart: Rubber band size grid.

### Staple leg length

How far the staple's legs reach below the crown, in millimetres, which sets how thick a stack it can bind. Within heavy-duty staples, leg length is the choice that matters, because the size code stays 23 while legs run from 6 to 24 mm. Too short and the legs will not reach through to clinch; Rapid also rates each heavy-duty size from a minimum stack, so an over-long staple on a thin stack is the wrong buy. Standard 26/6 and 24/6 staples are all 6 mm. [5] [9] [19] [20] [21] [22] [23]

Range: 4 to 24 mm. Standard staples are 6 mm (1/4 in). Heavy-duty ranges run 6 to 24 mm; Swingline sells 1/4 to 15/16 in.

Used as: filter, sortable. Data: on the listing, backfill cost none. Look for it as: In US titles as '1/4" Leg Length' or '1/2" Leg'; in EU codes as the second number (23/12 means 12 mm).
Chart: Leg length to sheets scale.

### Strip format

How many staples come joined in one strip, which decides whether the strip fits the stapler's channel. A full strip of standard staples holds 210; Swingline's 105-staple strips are for compact half-strip staplers and its heavy-duty strips hold 100. Its Optima High Capacity strips hold 125 and are for Optima 60 and 70 sheet staplers, though Optima Premium staples come in 210 strips. Some electric staplers take sealed cartridges instead. [10] [11] [14] [12] [13] [8] [5]

Values: full strip (210), half strip (105), heavy-duty strip (100), brand-specific strip, cartridge.

Used as: filter, shown on the card. Data: derived from listing fields, backfill cost low. Look for it as: Swingline brand titles carry '210 Per Strip' or '105 Per Strip'; retail titles (Quill) give only the box count.
When missing, standard 1/4 in staples are full strip and heavy-duty strips are 100. A brand-specific strip or sealed cartridge answer to staple_size sets this field to the matching value.

### Rubber band flat length

The band's length laid flat and unstretched, in inches, about half its relaxed loop. Width alone cannot pick a band, because length varies inside each width: #33 and #64 are both 3-1/2 in long at different widths, and 1/8 in bands run from 2-1/2 in (#31) to 7 in (#117B). The length decides what bundle the band goes round. Titles usually give it as the first dimension. [31] [33] [29] [32]

Range: 0.875 to 7 in. Standard charts run from 7/8 in (#8) to 7 in. Quill's office band titles run from 2-1/2 to 7 in.

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: In the title as the first dimension: '#33 Rubber Bands, 3-1/2" x 1/8"'. Some titles give only the number: 'Staples Economy #33 Rubber Bands, 700/Pack'.
When only the size number is given, look the length up in the Alliance chart.
Chart: Rubber band size grid.

### Wire grade

How strong the staple wire is, sold as standard, strong or premium, and superstrong, at the same size code. At the same code and leg, stronger wire pierces more sheets: Rapid rates its 24/6 Standard at 20 sheets and its 24/6 Strong at 30. Swingline sells premium staples on wire strength and chisel points that jam less. It is the reason two boxes of 26/6 carry different sheet ratings. [16] [17] [10]

Values: standard, strong or premium, superstrong.

Used as: shown on the card, sortable. Data: needs research, backfill cost low. Look for it as: In the product name on brand pages (Rapid 'Strong Staples 24/6', Swingline 'Premium'). Often missing on store-brand listings.
Read it from the brand line name; for store brands with no grade, record standard. Placing Swingline 'Premium' beside Rapid 'Strong' is our mapping; no source ranks grades across brands.

## Numbers worth computing

| Metric | Formula | Why |
|---|---|---|
| Stack thickness (mm) | `sheets * 0.1, where sheets is a stated sheet count or the top of the stack_sheets band` | Converts a sheet count into the thickness a staple leg or clip jaw must span. Rapid prints capacity this way on some staplers (ECO Halfstrip 2.5 mm/25 sheets, Supreme S17 3 mm/30 sheets), though not on all. [25] [26] [37] [38] |
| Binder clip capacity in sheets (sheets) | `clip_capacity_in * 25.4 / 0.1` | Puts clips on the same axis as staples so the sheet-count answer can filter both. A 5/8 in medium clip packed full holds roughly 140 to 165 sheets of 20 lb paper, at 97 to 114 micrometres a sheet. [27] [37] [38] |

## What you give up

- Longer legs bind thicker stacks, but a heavy-duty staple is rated for a band of sheets, not just a maximum. Rapid gives each heavy-duty size a minimum stack, so buy the leg for the stack you staple most. [19] [20] [21] [22] Board branch: "See more staples for thin stacks".
- A staple pierces and clinches, so the packet stays together, but it leaves holes and has to be pried out. A binder clip leaves the paper intact and comes off at once, so it suits papers that will be copied, scanned or split. [7] [5] Board branch: "See more clips that come off clean".
- Stainless steel staples and clips do not rust, but they cost more and are uncommon, so the range shrinks to a few lines. For papers handled this year, zinc-plated steel is fine; NARA says minor rust is not a concern. [5] [1] Board branch: "See more rust-proof fasteners".
- Natural rubber stretches more than synthetic, which is why most bands use it, but it hardens and cracks with heat, light and age. EPDM bands give up some stretch for longer life and no latex. [34] [32] [1] Board branch: "See more long-life bands".

## How to draw it

**Leg length to sheets scale** (scale, shows Staple leg length, Sheets held). One axis of leg length with each brand's sheet rating marked lets a buyer read off the staple for their stack, and shows where the brands overlap and where they spread by up to 30 sheets. Used today by Brand staple tables (Swingline sheet capacity by leg length; Rapid sheets per size code).. [9] [20] [21] [22]

**Rubber band size grid** (other, shows Rubber band width, Rubber band flat length). A grid of width rows and length columns shows what a size number means, and why #33 and #64 share a length but not a width. Used today by Alliance Rubber size chart, copied by distributors.. [31] [33]

## Words you will meet

- **Staple size code**. The label such as 26/6 or 23/12 that says which staplers a staple fits; the second number is the leg length in millimetres.
- **Crown**. The flat top of a staple that sits on the paper's face.
- **Leg**. One of the two wire points that go through the paper; also called the shank.
- **Clinch**. The bend the stapler's metal base puts in the legs under the stack, which is what holds the pages.
- **Anvil**. The grooved metal plate under the paper that bends the staple legs.
- **Pinning**. Turning the anvil so the legs bend outward, which makes the staple easy to pull out later.
- **Full strip**. A strip of 210 standard staples glued side by side, the length most desk staplers hold.
- **Half strip**. A strip of 105 staples for compact staplers with a shorter channel.
- **80 gsm or 20 lb paper**. Ordinary copy paper, the paper weight brands rate sheet capacity on.
- **Chisel point**. A staple leg cut to a sharp angled tip so it pierces cleanly and jams less.
- **Zinc-plated steel**. Steel wire with a thin zinc coat, the usual staple and clip material, which slows rust but does not stop it; also called galvanised.
- **Stainless steel**. Steel alloyed so it does not rust, sold for archival filing at a higher price.
- **Jaw capacity**. How thick a stack a binder clip opens wide enough to hold.
- **Flat length**. A rubber band's length laid flat and unstretched, about half its loop.
- **EPDM**. A synthetic rubber used for latex-free bands that resists heat and ageing.
- **Flat clinch**. A stapler that bends the legs flat against the back of the stack, so the packet lies flatter and the same staple can hold more sheets.
- **Black oxide**. A dark coating on the spring steel of most binder clips.

## Where we made a call

- Treat the staple code as a fit key: the second number is leg length, but names like No. 10 and 66/6 are not measurements. (confidence high). Wikipedia reads X/Y as wire gauge over leg in millimetres and lists exceptions; Rapid sells 66/6 and 44/6 electric-stapler codes. Ours, on those sources. [5] [15]
- Most standard desk staplers take both 26/6 and 24/6, so either answers the standard question. (confidence medium). Rapid lists both codes on its desktop staplers. US brands sell one 'standard 1/4 in' staple compatible with most staplers. Check the stapler where it names one code only. [24] [25] [26] [10]
- Brand sheet ratings at one leg length differ by up to 30 sheets and move with the stapler, so filter on the band. (confidence medium). Sources disagree. Rapid rates 23/12 at 60 to 90 sheets where Swingline rates 1/2 in at 90. Swingline rates 3/8 in at 60 heavy duty and 70 Optima, and 1/4 in Optima Premium at 25 in a standard stapler, 40 in a flat-clinch one. [9] [12] [13] [21]
- For long-term filing, stainless steel clips over a paper strip are the safer default than plastic clips. (confidence medium). Sources disagree. NARA uses stainless clips and notes office plastics degrade. West Virginia and Delaware university archivists prefer plastic or plastic-coated clips. We side with NARA as the national standard-setter. [1] [3] [4]
- Do not sell any rubber band as archival; offer a long-term buyer stainless or plastic clips, and keep the latex filter on any band shown. (confidence medium). Sources disagree. NARA removes rubber bands from records because they harden, break and stick, and keeps the papers together 'with a paper clip or a subfolder'. Alliance markets EPDM bands for archival filing. We side with NARA; the maker's claim is untested here. [1] [3] [32] [35]
- Binder clip size names are not standard; filter on capacity in inches. (confidence high). Sources disagree. Quill's large clip takes 1 in, JAM Paper's large 3/4 in, and Quill's guide says up to 1.25 in. Medium 1-1/4 in clips are 5/8 in in Quill and JAM titles; the guide says 0.645 in. [27]
- Loose brass paper fasteners and prong fasteners belong here; decorative craft brads go to crafts fasteners, and folders with built-in prongs to binders. (confidence medium). Ours. NPS lists brads among the paper fasteners archivists remove, so the office use is real. Decide by the use the listing sells: joining loose office papers stays here; scrapbook decoration or a folder with prongs goes to the sibling. [2]
