Value Collection 403204PR Hex Cap Screw 1/2-13 X 4 in Grade 2

Product Description

The VALUE COLLECTION 403204PR is a partially threaded hex head cap screw designed for general-purpose fastening applications in mechanical, structural, and industrial assemblies. Sized at 1/2-13 x 4 inches, it features a UNC thread standard with a 3/4-inch hex drive and is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance. The partial threading allows for a smooth shank section, which is useful when clamping material thicknesses require grip-length control. This fastener is commonly installed by maintenance technicians, millwrights, plumbers, and HVAC mechanics working on equipment mounting and structural connections.

This cap screw is suited for residential and light commercial applications where Grade 2 steel strength meets the load requirements. Typical uses include equipment bases, pipe hangers, structural brackets, fan assemblies, and general mechanical connections. The zinc plating makes it appropriate for indoor and mildly corrosive environments. Sold individually, with a minimum order quantity of 25 units, making it practical for stocking service vehicles or shop inventory.

Installation Notes

Installation requires a 3/4-inch open-end wrench, box wrench, or impact socket. Always ensure mating threads and tapped holes are clean and free of debris before installation. De-energize and lock out any equipment before fastening components on mechanical or electrical assemblies. Follow applicable torque guidelines for Grade 2 fasteners as published by the Machinery Handbook or equipment manufacturer specifications.
