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.

Disappointed with 1/4 inch product

by -

The first box of 1/4 inch product was not good. 25% of the product seemed miss cut. The screws would not screw easily go into the posts. Binding Depot replaced the first box with another and they worked fine. I'm not sure about recomending this product but Binding Depot handled this situation seamlessly.

Excellent product!

The product was well made. No issues with defective pieces. I used to make a nylon web belt for shooting competition. I needed only a few dozen and it was cheaper to buy bulk than pay the local hardware store almost 50 cents per piece.
