Frequently Asked Questions

Q: What are Chicago screws and how are they used in leather craft?

A: Chicago screws (also called binding screws or Chicago bolts) are two-part fasteners consisting of a threaded post and a matching screw cap. They are widely used in leather craft to join multiple layers of material — such as belt straps, wallet panels, or photo album covers — while allowing the pieces to be separated and reattached as needed. Their threaded design makes them far more versatile than permanent rivets.

Q: What sizes are available for these solid brass Chicago screws?

A: These brass Chicago screws are available in a variety of shaft lengths — 3, 4, 5, 6, 7, 8, 9, 10, and 12mm — with head diameters of either 8mm or 10mm and a shaft diameter of approximately 4mm (M3 thread). Each pack contains 10 pieces. The binding capacity is the distance between the two heads when fully closed, so choose a length that matches the thickness of your layered materials.

Q: Are these fasteners suitable for both decorative and functional use?

A: Yes! These solid brass Chicago screws feature a patterned decorative finish that looks polished and professional on visible areas of leather goods such as belts, wallets, and bags, while also providing a secure, reliable threaded connection for functional use in bookbinding, photo albums, straps, and cases.
