Value Collection 88548433 Hex Cap Screw 1/2-13 X 1-1/4 in Grade 5

Product Description

The Value Collection 88548433 is a fully threaded hex head cap screw designed for general mechanical and structural fastening applications. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener meets Unified National Coarse (UNC) thread standards at 1/2-13 thread size and a length under head of 1-1/4 inches. The zinc plating provides corrosion resistance in typical indoor and light-duty outdoor environments. This screw ships in a package quantity of 25, making it practical for job-lot purchasing by maintenance crews, contractors, and fabrication shops working in standard inch-measurement systems.

This fastener is suited for residential and commercial mechanical assemblies, equipment mounting, HVAC component fastening, plumbing fixture brackets, and general fabrication work where a 1/2-13 UNC fully threaded fastener is specified. The Grade 5 steel designation indicates medium-carbon steel with a minimum proof load appropriate for moderate-strength bolting applications. It is commonly used wherever UNC hex cap screws are called out in equipment installation or repair documentation.

• Zinc-plated finish for corrosion resistance in standard service environments
• Length under head: 1-1/4 inches
• Sold in a package quantity of 25 with a minimum order quantity of 1 package
• Inch measurement system with UNSPSC Code 31161501 classification

Compatibility

Designed as a standard 1/2-13 UNC Grade 5 hex head cap screw for use in any application calling out that thread size, material grade, and finish in inch-system mechanical assemblies.

Installation Notes

Installation is typically performed by millwrights, pipefitters, HVAC technicians, or general mechanics using a standard 3/4-inch hex wrench or socket. Always de-energize and lock out equipment before replacing fasteners in live assemblies. Verify the mating nut or tapped hole is rated for 1/2-13 UNC thread and Grade 5 proof load requirements. Do not substitute Grade 5 fasteners in applications specifying Grade 8 or higher without engineering approval.
