PFC Coupling Nuts - Coupling nut is a threaded fastener for joining two male threads, most commonly threaded rod. Fasteners are typically made of low-carbon steel. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.
