Value Collection 403010PR Hex Head Cap Screw 1/4-20 X 1/2 in

Product Description

The VALUE COLLECTION 403010PR is a fully threaded hex head cap screw designed for general-purpose fastening in a wide range of trade and industrial applications. It features a 1/4-20 UNC thread size with a 1/2-inch length under the head, manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. The hex drive requires a 7/16-inch wrench or socket. This fastener is a standard inch-system component suitable for light-duty structural and mechanical assembly work performed by electricians, plumbers, HVAC techs, and general maintenance professionals.

This screw is used in residential and commercial settings wherever a standard 1/4-20 UNC fully threaded fastener is required. Typical applications include equipment mounting, panel attachment, bracket installation, and general mechanical assembly. The zinc plating provides a barrier against light moisture exposure in indoor and sheltered outdoor environments. It is sold individually but carries a minimum order quantity of 100 pieces, making it appropriate for bulk stocking in service vans, shop inventory, or job-site supply.

Installation Notes

Installation requires a 7/16-inch open-end wrench, box wrench, or socket driver. De-energize or shut off any equipment before fastening or removing hardware on electrical enclosures or mechanical assemblies. Do not exceed the load ratings appropriate for Grade 2 steel fasteners in structural or high-vibration applications. Follow applicable codes such as NEC or IPC when using fasteners in code-governed installations.
