Value Collection KP86172 Hex Nut 7/16-20 Grade 8 Steel 50pk

Product Description

The VALUE COLLECTION KP86172 is a 7/16-20 UNF hex nut manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 steel provides high tensile strength suited for demanding fastening applications where standard hardware grades are insufficient. The zinc yellow dichromate coating adds corrosion resistance while meeting common industrial finishing standards. This nut features right-hand threading and measures 11/16 inches across flats with a height of 3/8 inches. It is packaged in a quantity of 50. Electricians, HVAC technicians, plumbers, and general mechanical contractors use Grade 8 hex nuts in structural and mechanical assemblies requiring reliable clamping force.

This hex nut is suited for residential and commercial mechanical, HVAC, plumbing, and electrical panel or structural fastening applications where a fine-thread, high-strength nut is required. The 7/16-20 UNF thread specification makes it compatible with 7/16-20 bolts and threaded rod used in equipment mounting, pipe hangers, vibration isolation bases, and similar trade installations. The 50-piece package format supports job-site use and service van restocking.

Compatibility

Designed for use with 7/16-20 UNF threaded bolts, cap screws, and threaded rod in mechanical, HVAC, plumbing, and electrical trade applications requiring a Grade 8 fine-thread hex nut.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with proper fastener torque and joint design requirements for Grade 8 hardware. Always de-energize or shut off equipment before servicing fastened assemblies. Use a properly sized socket or open-end wrench matched to the 11/16-inch across-flats dimension to avoid rounding the nut. Follow applicable mechanical and building codes, including AISC and manufacturer equipment guidelines, when specifying fastener grade and finish for structural or pressure-bearing connections.
