Value Collection MSC-67470807 Hex Nut 7/8-9 Grade 8

Product Description

The VALUE COLLECTION MSC-67470807 is a 7/8-9 UNC hex nut manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 steel provides high tensile strength suitable for demanding fastening applications in heavy-duty assemblies. The zinc yellow dichromate coating adds corrosion resistance while serving as a visual indicator of the Grade 8 classification. This nut measures 1.3125 inches across the flats and 0.75 inches in height, with a right-hand thread direction. Electricians, plumbers, pipefitters, HVAC technicians, and general trade professionals use this type of fastener in structural and mechanical connections throughout commercial and industrial installations.

This hex nut is suited for use in mechanical assemblies, equipment mounting, pipe support structures, conduit hangers, and general industrial fastening applications. The 7/8-9 UNC thread size and Grade 8 rating make it appropriate for high-load connections where standard hardware-grade nuts would be insufficient. Minimum order quantity is 15 pieces.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with torque requirements for Grade 8 fasteners. Always ensure the mating bolt or stud is also rated to Grade 8 or higher to maintain the integrity of the connection. Use a correctly sized 1-5/16 inch wrench or socket. Inspect threads for damage or contamination before assembly.
