What is a "Chicago screw"?

A Chicago screw is a type of fastening system that consists of two parts: a screw with a smooth, round head and a matching post or barrel. The screw is inserted through a hole in two pieces of material, and then the post is screwed onto the other end, securing the pieces together. Chicago screws are often used in leatherworking, bookbinding, and other crafts or industrial applications where a strong, removable connection is needed. They are commonly used for items like belts, straps, or binders, offering a neat and durable fastening solution.
