Value Collection 403210PR Hex Head Cap Screw 1/2-13 X 5.5 in

Product Description

The VALUE COLLECTION 403210PR is a partially threaded hex head cap screw designed for general-purpose fastening in structural and mechanical assemblies. It features a 1/2-13 UNC thread with a length under head of 5.5 inches, manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. The hex drive measures 3/4 inch across flats. This screw is a standard inch-series fastener suited for use in fabrication shops, mechanical contracting, HVAC equipment mounting, and other trade applications where a reliable, cost-effective threaded fastener is required.

This cap screw is well-suited for light-to-moderate structural connections in residential and commercial settings. Common applications include equipment base mounting, bracket assembly, and general mechanical fastening where Grade 2 tensile strength meets the load requirements. The zinc coating provides a serviceable level of protection in dry and mildly humid indoor environments. Trade professionals including HVAC technicians, pipefitters, millwrights, and general contractors commonly stock this size for field use.

Installation Notes

Install using a 3/4-inch combination wrench or socket with appropriate drive equipment. Ensure mating threads are clean and free of debris before installation. Follow applicable mechanical or structural codes for torque and fastener grade requirements specific to your assembly. Always de-energize and lock out equipment before performing any fastener work on live mechanical or electrical systems.
