Value Collection 403180PR Hex Head Cap Screw 1/2-13x1

Product Description

The VALUE COLLECTION 403180PR is a fully threaded hex head cap screw designed for general-purpose fastening applications across mechanical, structural, and industrial assemblies. Sized at 1/2-13 x 1 inch with a UNC thread standard, this fastener is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in dry and mildly humid environments. The 3/4-inch hex key drive allows installation with standard open-end, box-end, or socket wrenches. Licensed tradespeople and maintenance technicians working in HVAC, plumbing, electrical, and general mechanical service will find this a straightforward, code-compliant fastener for everyday bolted connections.

This cap screw suits residential and light commercial maintenance, equipment mounting, bracket fabrication, and general mechanical assembly where Grade 2 steel strength is sufficient. The fully threaded shank provides consistent thread engagement along the entire 1-inch length under the head, making it well suited for through-bolting thin materials or using with nuts and threaded inserts. It follows inch-series UNC thread standards and is compatible with standard 1/2-13 nuts and tapped holes.

Key Features

• Fully threaded shank for maximum thread engagement along the full 1-inch length under head
• 1/2-13 UNC inch-series thread standard for compatibility with standard nuts and tapped holes
• Grade 2 steel construction suited for general-purpose, non-structural fastening
• Zinc-plated finish provides basic corrosion resistance in dry and mildly humid environments
• 3/4-inch hex drive accommodates standard open-end, box-end, and socket wrenches

Compatibility

Designed as a standard inch-series UNC hex head cap screw compatible with any 1/2-13 threaded nut, tapped hole, or threaded insert following ASME B18.2.1 hex cap screw standards.

Installation Notes

Installation is performed with a 3/4-inch open-end, box-end, or socket wrench. Always ensure the mating nut or tapped hole matches the 1/2-13 UNC thread specification before installation. Do not exceed the rated load capacity of Grade 2 fasteners in high-stress or safety-critical structural joints, where higher-grade fasteners may be required by applicable codes. Inspect threads for damage before use and discard any fastener showing deformation or corrosion.
