Value Collection HHCSI21000500 Hex Head Bolt A307

Product Description

The VALUE COLLECTION HHCSI21000500 is a 1-8 UNC hex head bolt with a 5-inch length under head, manufactured from steel to ASTM A307 grade specifications. The bolt is partially threaded and carries a bright, uncoated finish. ASTM A307 establishes minimum tensile strength requirements for low-carbon steel fasteners, making this bolt a standard choice for structural and general-purpose bolted connections. It is sized using inch measurement standards and is sold individually. Electricians, pipefitters, millwrights, ironworkers, and general contractors routinely specify A307 hex bolts for equipment mounting, flange connections, and light structural assemblies.

This bolt is suited for residential and commercial construction applications, mechanical equipment installations, pipe flange connections, and general industrial fastening where ASTM A307 compliance is required. The partially threaded shank provides a smooth bearing surface in the grip length, which is preferred in certain shear-loaded connections. Its uncoated finish makes it appropriate for interior or controlled-environment applications where corrosion exposure is minimal.

Key Features

• ASTM A307 grade steel construction meets recognized fastener strength standards
• 1-8 UNC thread size with partial threading for a smooth shank grip length
• 5-inch length under head for use in thick stack assemblies or deep-reach connections
• Bright, uncoated finish suitable for interior and low-corrosion environments
• Inch measurement system for compatibility with standard US tooling

Compatibility

Designed as a general-purpose ASTM A307 hex head bolt for use in structural, mechanical, and equipment-mounting applications requiring a 1-8 UNC thread and 5-inch length under head.

Installation Notes

Installation should be performed by qualified tradespeople following applicable codes, including AISC or IBC provisions where structural connections are involved. Always de-energize and lock out equipment before fastening near electrical or mechanical systems. Use a properly sized hex wrench or socket to avoid rounding the hex head. Do not substitute this uncoated fastener in outdoor or high-humidity environments without verifying corrosion requirements for the application.
