Value Collection HCI50430550G-025BX Hex Head Cap Screw

Product Description

The VALUE COLLECTION HCI50430550G-025BX is a partially threaded hex head cap screw designed for structural fastening applications in trade and industrial settings. It carries a 7/16-14 UNC thread size, measures 5-1/2 inches under the head, and is manufactured from Grade 5 steel with a hot-dipped galvanized finish for corrosion resistance. The partial threading allows for a stronger grip through clamped materials, making it a reliable choice for high-load connections. Plumbers, HVAC mechanics, electricians, and general contractors commonly use fasteners of this type when securing equipment, brackets, flanges, and structural assemblies.

This fastener is suited for both residential and commercial applications where inch-series UNC fasteners are specified. Typical use cases include equipment mounting, structural steel connections, duct and pipe support framing, and general mechanical assembly. The hot-dipped galvanized coating makes it appropriate for outdoor or moderately corrosive environments where bare steel fasteners would be prone to rust. It conforms to inch measurement standards and is sold in multiples of 25 units minimum.

Key Features

• Grade 5 steel construction provides solid tensile strength for structural fastening tasks
• Hot-dipped galvanized finish delivers corrosion resistance for outdoor and humid environments
• Partially threaded shank improves clamping force across joined materials
• 7/16-14 UNC thread standard ensures compatibility with standard inch-series nuts and tapped holes
• 5-1/2 inch under-head length accommodates thicker material stacks

Compatibility

Designed as a standard inch-series UNC hex head cap screw compatible with 7/16-14 nuts, washers, and tapped holes following Unified National Coarse thread specifications.

Installation Notes

Installation should be performed by a qualified mechanic, contractor, or tradesperson using the appropriate hex wrench or socket. Always ensure the receiving nut or tapped hole matches the 7/16-14 UNC thread specification before installation. De-energize and isolate any equipment before fastening components in electrical or mechanical assemblies. Do not use impact tools at excessive speed on galvanized fasteners, as this may damage the coating and reduce corrosion protection.
