Value Collection 88548086 Hex Head Cap Screw 1/4-20 X 1/2 in 50pk

Product Description

The VALUE COLLECTION 88548086 is a 1/4-20 x 1/2-inch Grade 5 steel hex head cap screw with a zinc-plated finish and partial threading. It follows the Unified National Coarse (UNC) thread standard and is driven with a 7/16-inch hex key or wrench. The zinc plating provides corrosion resistance for general-purpose fastening in mechanical assemblies, equipment mounting, and trade service work. This screw is a standard hardware item used by HVAC technicians, plumbers, electricians, and other trade professionals for panel attachment, bracket mounting, and component securing tasks.

This fastener is suited for residential and light commercial applications where a Grade 5 medium-strength steel screw is appropriate. It ships in a package quantity of 50, making it practical for service vans, job boxes, and shop stock. The partial threading provides clamping force when drawing two surfaces together, which is appropriate for through-hole fastening into a nut or threaded insert. Typical uses include equipment enclosure assembly, ductwork bracket hardware, electrical panel component mounting, and general mechanical fastening across trade disciplines.

Key Features

Compatibility

Designed as a standard UNC 1/4-20 hex head cap screw compatible with any application requiring a Grade 5 steel fastener of this thread size and length under head.

Installation Notes

Install with a 7/16-inch open-end wrench, box wrench, or socket driver. Ensure the mating thread or nut matches the 1/4-20 UNC specification before driving. Do not exceed appropriate torque for Grade 5 hardware in the application material. Power down or de-energize any equipment before installing or removing fasteners on energized enclosures or panels.
