Value Collection HCI51120275G Hex Head Cap Screw

Product Description

The VALUE COLLECTION HCI51120275G is a fully threaded hex head cap screw designed for heavy-duty fastening applications in structural, mechanical, and industrial assembly work. It measures 1-1/8-7 UNC thread size with a 2-3/4 inch length under head and is manufactured from Grade 5 steel with a hot-dipped galvanized finish that provides corrosion resistance in exposed or outdoor environments. The full-thread configuration runs the entire usable length, maximizing grip and thread engagement across the clamped material. Tradespeople and contractors reach for this fastener when a high-strength, corrosion-resistant hex cap screw is required for structural connections or equipment mounting.

This hex cap screw suits residential and commercial construction, heavy equipment assembly, structural steel connections, and general mechanical fabrication. It is commonly used in applications where UNC thread pattern and a galvanized finish are specified, including outdoor mounting hardware, utility structures, and industrial frames. The hot-dipped galvanized coating makes it appropriate for environments with moisture exposure where bare or zinc-plated fasteners would corrode prematurely.

Key Features

• Grade 5 steel construction delivers high tensile strength for structural and mechanical fastening
• Hot-dipped galvanized finish provides durable corrosion resistance in wet or outdoor environments
• Fully threaded shank maximizes thread engagement throughout the entire clamped length
• 1-1/8-7 UNC thread standard ensures broad compatibility with standard inch-series nuts and tapped holes
• 2-3/4 inch length under head suits medium-depth clamping applications

Compatibility

Designed as a standard inch-series UNC hex head cap screw compatible with 1-1/8-7 nuts, washers, and tapped holes conforming to Unified National Coarse thread standards.

Installation Notes

Installation is typically performed by millwrights, ironworkers, electricians, or general contractors using a standard hex wrench or impact driver with the appropriate socket. Always power down or de-energize adjacent equipment before working in close proximity to live systems. Follow applicable structural or mechanical specifications and relevant building codes when using fasteners in load-bearing connections. Do not reuse fasteners that show thread damage, corrosion, or deformation.
