Value Collection HCI31250325N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31250325N-005BX is a fully threaded hex head bolt designed for structural and heavy-duty fastening applications. It features a 1-1/4-7 UNC thread size and a 3-1/4 inch length under head, manufactured from uncoated steel to ASTM A325 structural bolt standards. The A325 grade indicates high-strength performance suitable for steel-to-steel connections in load-bearing assemblies. The bright, uncoated finish means no additional coating process has been applied, making it appropriate for installations where coating is specified separately or not required. Licensed tradespeople and construction professionals working with structural steel connections will find this bolt meets the dimensional and mechanical requirements of ASTM A325.

This bolt is suited for structural steel construction, heavy equipment assemblies, and industrial fastening applications where high-strength UNC fasteners are specified. The fully threaded configuration allows maximum thread engagement along the full length of the shank, which is preferred in applications requiring deep thread contact or adjustable clamping depth. It is commonly installed by ironworkers, millwrights, and mechanical contractors working on structural frames, base plates, and heavy machinery mounts.

Compatibility

Designed as a standard ASTM A325 fully threaded hex head bolt for structural steel and heavy-duty industrial fastening applications requiring 1-1/4-7 UNC thread specifications.

Installation Notes

Installation should be performed by qualified tradespeople following applicable structural codes, including AISC and RCSC specifications for high-strength bolted connections. Always confirm mating nut thread class and hole clearance before installation. Torque or tension requirements for A325 bolts must be determined from applicable project engineering specifications — do not assume a default value. De-energize and lock out any adjacent energized equipment before working in proximity to electrical systems.
