Value Collection HCI30620550N-010BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI30620550N-010BX is a Grade A325 steel hex head bolt designed for structural and heavy-duty fastening applications. It features a 5/8-11 UNC thread and a 5-1/2 inch length under head with partial threading along the shank. The uncoated, bright finish leaves the steel in its natural state, making it suitable for applications where a coating is not required or where field treatment will be applied. At 0.678 pounds, this bolt meets ASTM A325 structural bolt standards, making it a recognized choice for steel-to-steel connections in construction and industrial work.

This bolt is suited for structural steel connections, heavy equipment assembly, and construction framing applications. Partial threading provides a bearing shank section that resists shear loads in bolted joints, a requirement in many structural steel connections governed by AISC and ASTM specifications. It is typically installed by ironworkers, structural contractors, millwrights, and maintenance professionals working with steel framing, base plates, and mechanical equipment mounts.

Key Features

• Partially threaded shank provides a full bearing section for shear-loaded joints
• Bright uncoated finish suitable for galvanizing, painting, or use as-is
• Hex head drive accepts standard hex sockets and open-end wrenches
• Inch measurement system with UNC thread standard

Compatibility

Designed as an ASTM A325 structural hex head bolt for use with standard 5/8-11 UNC hex nuts and hardened washers in structural steel connections.

Installation Notes

Installation should be performed by qualified tradespeople familiar with structural bolt torque requirements per AISC or RCSC specifications. Always power down or de-energize any adjacent electrical systems before working in confined steel structures. Use a calibrated torque wrench or tension-control installation method appropriate for A325 bolts. Do not reuse structural bolts that have been fully tensioned, as they may have yielded.
