Value Collection HCI30620400NG-010BX Hex Head Bolt

Product Description

The VALUE COLLECTION HCI30620400NG-010BX is a 5/8-11 UNC hex head bolt designed for structural and heavy-duty fastening applications. It is manufactured from steel to ASTM A325 material grade specifications and features a hot-dipped galvanized finish for corrosion resistance. The bolt measures 4 inches in length under the head and is partially threaded, which is standard for structural bolting where the shank bears load in the grip zone. At 0.271 pounds per fastener, this bolt is suited for use by ironworkers, structural steel contractors, and maintenance mechanics working on connections that require A325-rated hardware.

This bolt is used in structural steel connections, steel-to-steel bolted joints, and heavy equipment mounting applications that call for ASTM A325 compliant hardware. The partially threaded shank is appropriate for connections where the unthreaded grip length needs to span the full material thickness. The hot-dipped galvanized finish makes it suitable for exterior and exposed environments where bare steel fasteners would be prone to rust. It is sold individually and is compatible with standard 5/8-inch structural nuts and washers used in inch-measurement fastening systems.

Key Features

• ASTM A325 material grade steel meets structural bolting standards
• Hot-dipped galvanized finish provides corrosion resistance for exterior use
• Partially threaded shank supports load-bearing in the bolt grip zone
• 5/8-11 UNC thread size is compatible with standard 5/8-inch structural nuts
• 4-inch length under head accommodates typical structural connection stack-ups
• Inch measurement system for use with standard imperial fastener tooling

Compatibility

Designed as an OEM-style structural replacement or new-installation fastener for applications requiring ASTM A325 compliant hex head bolts in 5/8-11 UNC thread size with a 4-inch length under head.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural mechanics following AISC and RCSC bolt installation specifications. Snug-tighten the connection before applying final tension; do not reuse A325 bolts that have been fully tensioned. Use appropriate impact or torque tooling rated for 5/8-inch structural bolts, and ensure washers are used as required by the connection design. Always verify that the unthreaded shank length is sufficient to fill the grip of the connection before torquing.
