Value Collection KP86163 Hex Nut 1/2-13 Grade 8 50-pack

Product Description

The VALUE COLLECTION KP86163 is a Grade 8 steel hex nut sized 1/2-13 UNC, finished in zinc yellow dichromate for corrosion resistance. It features a right-hand thread pattern and is built to Grade 8 strength standards, making it suitable for high-load fastening applications in mechanical, structural, and industrial assemblies. The zinc yellow dichromate coating provides a secondary layer of protection against oxidation and environmental exposure. This package contains 50 nuts, making it a practical choice for contractors, maintenance technicians, and tradespeople who need reliable fasteners in quantity.

This hex nut is used in a wide range of commercial, industrial, and trade applications where high-strength fastening is required. Typical use cases include structural steel connections, heavy equipment assembly, HVAC equipment mounting, and general mechanical fabrication. The 1/2-13 UNC thread size is one of the most common coarse-thread fastener specifications in North American trade work, making this nut a shop and field staple for plumbers, HVAC techs, electricians, and general contractors alike.

Installation Notes

Installation is performed by hand-threading onto a compatible 1/2-13 UNC bolt or threaded rod, then torquing to the specification required by the assembly design. Always de-energize equipment and relieve system pressure before replacing fasteners in mechanical or utility systems. Use a calibrated torque wrench when final torque values are specified by the equipment manufacturer or applicable code. Do not mix Grade 8 nuts with lower-grade hardware in high-load connections.
