Value Collection 57NF Hex Nut 9/16-18 Un Steel

Product Description

The VALUE COLLECTION 57NF is a 9/16-18 UN hex nut designed for general-purpose fastening applications in industrial, mechanical, and structural assemblies. Manufactured from steel with a zinc-plated finish, this nut provides corrosion resistance suitable for indoor and moderate-exposure environments. It features a right-hand thread direction conforming to the UN thread standard and measures 7/8 inches across flats with a height of 31/64 inches. Licensed tradespeople and assembly technicians use this nut where a reliable, standard-profile hex fastener is required. The zinc plating adds a layer of protection against oxidation without altering the dimensional profile of the fastener.

This hex nut is suited for use in fabrication, maintenance, and repair work across trades including mechanical, structural, and general industrial applications. It is compatible with 9/16-18 UN male-threaded fasteners such as bolts, studs, and threaded rods. The right-hand thread pattern follows the standard tightening convention, making it straightforward to install in conventional assemblies. It is appropriate for use in both shop and field environments where a standard steel hex nut is specified.
