Value Collection MP39617 Hex Nut 5/8-18 Grade 8

Product Description

The VALUE COLLECTION MP39617 is a Grade 8 steel hex nut with a 5/8-18 UNF thread size and a zinc yellow dichromate finish. It is designed for high-strength fastening applications where corrosion resistance and mechanical durability are required. The right-hand thread pattern and unified fine thread standard make it a reliable choice for bolted connections in demanding environments. At 0.04 pounds per unit, this compact nut measures 15/16 inches across flats and 35/64 inches in height, fitting standard 5/8-18 hex fastener assemblies. Licensed tradespeople and maintenance technicians working on mechanical, HVAC, or industrial equipment commonly use this nut in structural and component fastening tasks.

This hex nut is suited for use in residential and commercial mechanical systems, equipment mounting, and industrial assembly work where a fine-thread Grade 8 fastener is specified. The zinc yellow dichromate finish provides a layer of corrosion protection suitable for general-purpose indoor and light-duty outdoor installations. It is commonly used in equipment enclosures, structural brackets, motor mounts, and similar bolted assemblies that require a high-strength fine-thread nut.

Installation Notes

Installation requires a standard 15/16-inch wrench or socket. Power down and de-energize any associated equipment before servicing fasteners on electrical or mechanical enclosures. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly. Avoid mixing thread standards or grades, as mismatched hardware can compromise joint integrity.
