Value Collection 319600BR Hex Nut 5/8-18 Unf Grade 2 Zinc

Product Description

The VALUE COLLECTION 319600BR is a 5/8-18 UNF hex nut manufactured from Grade 2 steel with a zinc-plated finish. It features a right-hand thread pattern and measures 15/16 inches across the flats with a height of 0.5469 inches. This is a standard fastener used across mechanical, structural, and light industrial assembly applications. Installation is performed by maintenance technicians, pipefitters, electricians, and general tradespeople wherever a 5/8-18 fine-thread nut is required to secure bolts, studs, or threaded rod.

This hex nut suits residential and commercial applications where a fine-thread 5/8-18 UNF fastener is specified. Common install scenarios include equipment mounting, bracket assembly, conduit support structures, and general mechanical assembly. The zinc plating provides basic corrosion resistance for indoor and light-duty outdoor use. It does not meet military specifications and is intended for standard commercial fastening duties.
