Book Binding Screws - Copper-plated - Rose-gold coloured
These book binding screws (aka chicago screws or interscrews) are available from 2 to 10 mm length.
All binding screws are copper plated and the colour is similar to - you guessed it - copper, or rose-gold.
Please be aware that screws up to 3.5 mm length have an open post (see pictures).
Ideal to hold together several pages of documents or swatch books, depending on the length you choose.
The longer the binding screw, the more it can hold.
The binding screws come in pairs (screws and posts), which you can easily put together by hand or use a screwdriver.
Reusable: simply unscrew.

Book Binding Screw Size Chart
A binding screw's length is the post height between the two heads — in other words, the maximum total thickness it can hold. That can be paper, greyboard, leather or any mix of them. Use the chart below to find the right length for what you're binding.
Each sheet of paper has two pages — a front and a back — so a 100-page document printed double-sided is 50 sheets. Work out your size in three steps: measure your paper stack (80 gsm paper is roughly 0.1 mm a sheet, so 50 sheets ≈ 5 mm), add both covers (2 mm greyboard each side adds 4 mm), then round up to the next length. If you only know the page count, our Spine Width Calculator will estimate it for you.
| Screw Length |
Approx. Sheet Capacity (80 gsm paper / 1 sheet ≈ 0.1 mm) |
With Covers (2 mm board each side) |
Best for |
|---|---|---|---|
| 2 mm | 20 sheets / 40 pages | paper or card covers only | Swatch cards, tags, mini journals, paper crafts |
| 3.5 mm | 35 sheets / 70 pages | paper or card covers only | Small notebooks, restaurant menus, labels |
| 5 mm | 50 sheets / 100 pages | 10 sheets | Sketchbooks, recipe books, leather bags, leather notebooks |
| 7 mm | 70 sheets / 140 pages | 30 sheets | Craft journals, wedding albums, leather belts and pet collars |
| 10 mm | 100 sheets / 200 pages | 60 sheets | Photo books, scrapbooks, thicker leather covers |
Note: The sheet capacities and "best for" recommendations are approximate and can vary based on paper thickness and binding style. Always test with your specific materials to ensure a perfect fit.
Need more than 10 mm? Screws of 7 mm and longer take a 10 mm extension, and screws of 10 mm and longer take a 5 mm extension. Stack them to build almost any capacity.

Common questions
How do I convert a page count into a screw length?
How do I convert a page count into a screw length?
Every sheet has two pages, so a 100-page double-sided document is 50 sheets. At 80 gsm that is about 5 mm of paper. Add your covers, then round up. Our Spine Width Calculator does the arithmetic if you only know the page count and paper weight.
My paper isn't 80 gsm. How do I adjust?
My paper isn't 80 gsm. How do I adjust?
Gsm measures weight, not thickness. A bulky uncoated paper can be noticeably thicker than a coated sheet of the same gsm, so treat these as a starting point: 80 gsm ≈ 0.10 mm, 100 gsm ≈ 0.13 mm, 120 gsm ≈ 0.15 mm, 160 gsm ≈ 0.20 mm and 300 gsm card ≈ 0.35 mm. To be sure, stack 20 sheets, measure the stack with a caliper and divide by 20.
Should I choose the exact length or go up a size?
Should I choose the exact length or go up a size?
Go up. A post filled to its exact capacity binds tightly and the pages won't turn cleanly — aim to fill about 90% of the post. If you are between two lengths, the longer one still closes properly on a thinner stack; you'll just see a little more of the post.
Can I take the binding apart again?
Can I take the binding apart again?
Yes. Screw-post binding is fully reversible: unscrew the head, add or remove sheets, screw it back. That is why it suits portfolios, swatch books and anything that gets updated.
