It is built from a brass body with a nickel finish, giving it the corrosion resistance and mechanical strength needed for repeated field mating and unmating in RF interconnect systems. The nut is intended for use with BNC jacks, serving as the rotating collar that tightens the connection and maintains the 50-ohm interface's mechanical integrity. ## Construction and Finish The body material is brass, chosen for its machinability and electrical conductivity, and the body finish is nickel, which provides a hard, wear-resistant surface that resists oxidation and maintains a consistent ground path through the shell. The color is listed as silver, consistent with the nickel plating. This is a standard construction for BNC hardware that sees moderate mating cycles in lab, test, and communications equipment.","metaTitle":"Amphenol 31-5652 BNC Nut, Nickel-Plated Brass, Bulk","metaDescription":"Amphenol 31-5652 BNC coupling nut, nickel-plated brass, for BNC jacks.
