Chicago Screws were invented back in 1872 when the Chicago Screw Company first established its business. Simple enough the name was conceptualized with its manufacturer “Chicago Screw”.What I like most about Chicago screws is that they're stronger than rivets and can handle much more stress.
Barrel nuts, binder posts, and Chicago screws are all types of mating fasteners. A mating fastener consists of an internally-threaded, barrel-shaped body with a protruding flange, to which an externally-threaded mating bolt (most often a machine screw) is paired.
