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, 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.
