Manufactured from Grade 2, Grade A steel with a clear zinc finish, this nut provides corrosion resistance suitable for general mechanical and structural assembly. The right-hand thread conforms to standard UNF specifications. With a width across flats of 2.25 inches and a height of 1.281 inches, it is sized for use with standard wrenches in industrial, trade, and maintenance applications. Licensed tradespeople in mechanical, plumbing, and construction trades commonly install this hardware during equipment assembly and repair work.

This hex nut is suited for use in residential, commercial, and light industrial settings wherever a 1-1/2-12 UNF threaded fastener connection is required. Typical applications include mechanical equipment assembly, piping support structures, pump and motor mounting, and general structural fastening.
