Taiyuanfeng High-Quality Chicago Screws / Sex Bolts | Precision Connection, Strong & Smooth

What Are Chicago Screws (Sex Bolts / Binding Screws)?

Chicago screws, also known as sex bolts, binding screws or barrel nuts, are special fasteners consisting of a threaded male post and a mating female barrel with internal threads. Unlike ordinary screws, they clamp together from both ends, leaving a smooth, flush surface and allowing repeated assembly and disassembly. They are widely used in leather goods (belts, bags), binders, display stands, helmets, furniture hardware, and various industrial quick-release structures.

Thanks to their unique male-female design, Chicago screws provide both robust mechanical connection and aesthetically pleasing hidden fastening, making them a favorite among designers and engineers.
