Brighton Best's 1/2 in. x 13 TPI Yellow-Zinc Hex Nut features a six-sided exterior that allows installation and removal with a standard wrench or socket, making it practical for routine assembly and service work. The coarse thread provides good thread engagement while helping simplify installation in common fastening applications. Yellow zinc plating adds a recognizable finish while helping protect the underlying steel from corrosion. This hex nut is intended for use with matching 1/2 in.-13 threaded fasteners where a conventional, reusable nut is required.
