Value Collection KP86160 Hex Nut 5/16-18 Grade 8 Pack 100

Product Description

The VALUE COLLECTION KP86160 is a 5/16-18 UNC 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 delivers corrosion resistance and serves as a visual indicator of the Grade 8 specification. These nuts measure 0.5 inches across the flats and 17/64 inches in height, conforming to standard UNC dimensional tolerances. Sold in a pack of 100, this SKU is appropriate for contractors, maintenance crews, and trade professionals who need reliable high-strength fasteners in volume.

The KP86160 hex nut is suited for structural, mechanical, and equipment assembly applications where Grade 8 fastener strength is required. Common uses include mounting heavy-duty equipment, securing structural steel connections, and assembling machinery frames in commercial and industrial settings. The right-hand thread direction follows standard practice for the majority of fastening applications. The 5/16-18 UNC thread size is widely used across HVAC equipment frames, electrical enclosures, plumbing support structures, and general mechanical assemblies encountered in the trades.

Installation Notes

Installation should be performed by qualified tradespeople following applicable mechanical and structural codes. Always verify that mating bolt or stud grade and thread specification match before assembly. Use a calibrated torque wrench and refer to published Grade 8 torque specifications for the 5/16-18 thread size from a recognized fastener standard. Do not mix thread standards or grades within the same fastener assembly.
