Value Collection KP86170 5/16-24 Grade 8 Hex Nut 100-pack

Product Description

The VALUE COLLECTION KP86170 is a Grade 8 steel hex nut with a 5/16-24 UNF thread size and a zinc yellow dichromate finish. Grade 8 steel provides high tensile strength suited for demanding fastening applications where standard hardware would fail under load. The zinc yellow dichromate coating adds corrosion resistance while meeting common industrial finishing standards. This nut features a right-hand thread, a width across flats of 0.5 inches, and a height of 17/64 inches. Sold in a pack of 100, it is well suited for bulk use in mechanical assembly, equipment fabrication, HVAC component mounting, and general trade applications.

This hex nut is used in a wide range of residential and commercial trade applications where a fine-thread, high-strength fastener is required. The 5/16-24 UNF thread is common in mechanical and HVAC equipment assemblies, electrical enclosure mounting, and structural component attachment. Electricians, HVAC technicians, plumbers, and general fabricators regularly use Grade 8 fine-thread nuts in applications subject to vibration or high-load conditions. The 100-piece pack supports job-site stocking and service van inventory.

Installation Notes

Installation is performed by hand-starting the nut onto a clean, undamaged 5/16-24 UNF male thread before tightening with an appropriate wrench or socket. Always verify thread direction and thread class compatibility before assembly. Do not mix Grade 8 nuts with lower-grade fasteners in high-load joints. Follow applicable torque guidelines from the equipment manufacturer or relevant industry standards for the assembly being serviced.
