Chicago screw for leathercraft
Chicago Screws — Removable Fasteners for Leather
A Chicago screw (also known as a binding screw or screw post) is a two-part fastening system consisting of a male screw and a female post that screw together through the leather. Its main advantage is that the assembly is removable and adjustable. Using a simple screwdriver, you can tighten, replace, or swap out a component whenever needed without damaging your project. It is the ideal solution for making stitch-free belts, bag handles, harnesses, and collars.
Our steel Chicago screws are available in several finishes: antique brass, black nickel, brass plated, and nickel plated.
How do you install a Chicago screw?
Installation is quick and requires only three tools: a hole punch matching the diameter of the post, a mallet, and a screwdriver. Punch a hole where required, insert the female post from one side and the male screw from the other, then tighten securely with a screwdriver. The assembly is ready immediately and can be disassembled at any time.

Frequently Asked Questions About Chicago Screws
What is the difference between a Chicago screw and a rivet?
A rivet creates a permanent fastening: once installed, it cannot be removed without being destroyed. A Chicago screw, on the other hand, is removable and can be unscrewed at any time to adjust, replace a part, or change the finish. Chicago screws are preferred for assemblies that may need future modifications (belts, watch straps, adjustable components), while rivets are better suited for permanent fastenings.
How do you install a Chicago screw?
You will need a hole punch matching the diameter of the post, a mallet, and a screwdriver. Punch a hole through the leather, place the female post underneath and the male screw on top, then tighten them securely with a screwdriver. The process takes only a few seconds, and the assembly remains fully removable.
What size Chicago screw should I choose?
The screw length should match the total thickness of the leather layers being joined. If the screw is too short, it will not hold securely; if it is too long, the assembly will have unwanted play. Our Chicago screws are available in several sizes, and some packs include multiple lengths to suit different leather thicknesses. Measure the total thickness of your project before selecting the appropriate size.
Are Chicago screws strong?
Yes. Our steel Chicago screws provide excellent strength and durability. For heavily stressed applications such as thick belts or harnesses, choose a larger diameter screw. When properly tightened, they remain secure during normal use. For added security, you can apply a small drop of thread-locking adhesive or glue to help prevent loosening.
