Value Collection HHCSI20750225-015BX Hex Head Bolt

Product Description

The VALUE COLLECTION HHCSI20750225-015BX is a fully threaded hex head bolt designed for general structural and mechanical fastening applications. It features a 3/4-10 UNC thread size and a 2.25-inch length under head, manufactured from uncoated steel to the ASTM A307 Grade A307 standard. The hex drive head accepts standard wrenches and impact tools, making installation straightforward in both shop and field environments. This bolt is suited for use by ironworkers, pipefitters, electricians, and general contractors wherever a reliable, code-recognized carbon steel fastener is required.

This bolt is appropriate for low-carbon steel structural connections, equipment mounting, and general-purpose mechanical assembly in both residential and light commercial construction. Its fully threaded body provides clamping engagement along the entire shank length, which is useful when through-bolting thinner materials or when nut position along the bolt must be adjustable. ASTM A307 is a widely accepted standard for general fastening where higher-strength grades such as A325 or A490 are not required by the design specification.

Key Features

• 3/4-10 UNC thread size for compatibility with standard 3/4-inch hex nuts and threaded inserts
• 2.25-inch length under head for through-bolt and structural assembly applications
• Fully threaded body allows full nut engagement anywhere along the shank
• ASTM A307 Grade A307 certified for use in recognized structural and mechanical specifications
• Uncoated bright finish — suitable for indoor or protected environments where corrosion is not a primary concern
• Inch measurement system for direct compatibility with standard U.S. hardware

Compatibility

Designed as an ASTM A307 Grade A307 compliant general-purpose hex head bolt for use with standard 3/4-10 UNC hex nuts, flat washers, and lock washers in structural and mechanical fastening assemblies.

Installation Notes

Installation should be performed by qualified tradespeople following applicable structural or mechanical codes, including AISC and ASTM standards where structural connections are involved. Power down or de-energize any equipment before fastening components in electrical or mechanical enclosures. Use calibrated torque wrenches when a specific clamp load is required by the design engineer — torque values are not included here and must be sourced from the applicable design specification. Uncoated fasteners should not be used in exposed outdoor or high-humidity environments without additional corrosion protection.
