Chicago screws are sold in sets of 100 (100 screws & 100 posts). Screw post extensions are 100 per box.



Screw posts, also known as Chicago screws or book binding posts, are extremely versatile binders that allow loose documents of practically any shape or size to be securely bound together. These low-cost, reusable Chicago screws enable you to easily change out bound documents, making them a great choice for price books, menus, swatch books, architectural and engineering drawings, and much more. Our high quality, antique brass-colored aluminum screw posts provide an easy-to-use alternative to other binding methods at an exceptionally low price point. Their two-piece construction allows for no-fuss updates, which is why they're an ideal choice for applications that require frequent updates. They are also easy to expand, with a number of screw post extensions readily available.

Best value out there. Good quality, great price. Good service

Wrong product sent!

After searching for days for the perfect book binding screw for a design project I was thrilled to find them on your site. It was a tight deadline on my project and I ordered black screws and had them sent directly to my printer so his staff could bind the booklets when completed. Sadly, we were not sent the black and instead received silver. Due to our tight deadlines we had no time to call and have the correct ones sent so had to use the silver. My design project was compromised as the black would have been outstanding and would have gone with the booklet for which it was designed.

Great product!
