Value Collection HCI30620325N-005BX Hex Bolt 5/8-11 A325

Product Description

The VALUE COLLECTION HCI30620325N-005BX is a 5/8-11 hex head bolt designed for structural and heavy-duty fastening applications. It is manufactured from steel to ASTM A325 material standards, with a bright uncoated finish and partial threading along the shank. The bolt measures 3.25 inches in length under head, using the Unified National Coarse thread standard. Grade A325 fasteners are commonly used in steel-to-steel connections and structural assemblies where high-strength clamping force is required. This bolt is sold in a minimum order quantity of 5 units.

This bolt is suited for structural steel connections, equipment mounting, and heavy mechanical assemblies in commercial and industrial settings. The partial threading is standard for A325 structural bolts, allowing the unthreaded shank to bear shear loads in bolted connections. Ironworkers, millwrights, and mechanical contractors regularly specify ASTM A325 fasteners where load-rated, high-strength connections are required by engineering drawings or project specifications.

Key Features

• Grade A325 steel construction meets ASTM A325 structural bolt standards
• 5/8-11 UNC thread size for compatibility with standard heavy-duty nuts and tapped connections
• Partial threading allows shank to carry shear loads in structural connections
• Bright uncoated finish — suitable for indoor or protected structural applications
• 3.25-inch length under head accommodates multi-layer steel stack-ups and thick connection plates

Compatibility

Designed for use with standard 5/8-11 UNC heavy hex nuts and washers in structural steel and mechanical fastening applications meeting ASTM A325 specifications.

Installation Notes

Installation should be performed by qualified ironworkers, millwrights, or mechanical contractors following applicable structural codes and project engineering requirements. Torque values must be determined from the applicable code or engineer of record specifications — do not estimate torque for structural connections. Always use appropriate hardened washers under the head and nut as required by AISC or project specifications. Verify bolt grip length against connection stack-up before installation to ensure thread engagement is correct.
