The VALUE COLLECTION R50000377 is a Grade 8 steel hex nut with a 7/8-14 thread size conforming to the Unified National Fine (UNF) thread standard. It features a right-hand thread direction and an uncoated, bright finish. At 1.3125 inches across the flats and 1-5/32 inches in height, this nut is suited for high-strength fastening applications where tensile and proof load requirements exceed those of lower-grade fasteners. Grade 8 classification indicates a higher strength level compared to Grades 2 and 5, making it appropriate for demanding mechanical assemblies. Licensed tradespeople and maintenance professionals working with heavy equipment, structural connections, and industrial machinery commonly use this hardware.
This hex nut is used in industrial, commercial, and heavy-duty mechanical assembly applications. It is appropriate wherever a 7/8-14 UNF right-hand thread fastener with high-strength characteristics is required. Typical install scenarios include equipment frames, vehicle and trailer hardware, hydraulic component mounting, and structural bolted connections that call for Grade 8 fastener specifications.
Designed as a standard replacement or assembly hex nut for applications requiring a 7/8-14 UNF Grade 8 right-hand thread fastener.
Installation is typically performed by maintenance technicians, millwrights, or equipment mechanics using a standard combination or box-end wrench sized for 1-5/16 inches across flats. Always ensure the mating bolt or stud is also rated to Grade 8 or equivalent to maintain the integrity of the joint. Inspect threads on both the nut and mating fastener for damage or contamination before assembly. Follow applicable torque specifications for the joint design as established by the equipment manufacturer or relevant industry standards.
