Value Collection HCI30620550NG-010BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI30620550NG-010BX is a 5/8-11 hex head bolt manufactured from steel to ASTM A325 structural bolt standards. It measures 5.5 inches in length under the head and features a hot-dipped galvanized finish for corrosion resistance in demanding environments. The bolt is partially threaded, which is standard for structural connections where clamping force is distributed through the unthreaded shank. At 0.678 pounds, this is a heavy-duty fastener suited for steel-to-steel connections in structural and industrial applications. Licensed trades including ironworkers, steel erectors, structural contractors, and mechanical trades install this type of hardware on job sites governed by AISC and related structural codes.

This bolt is designed for structural steel connections, heavy equipment assembly, bridge fabrication, and industrial framing applications. The 5/8-11 UNC thread specification and A325 material grade make it a go-to fastener wherever high-strength structural bolting is specified by an engineer or project drawing. The hot-dipped galvanized finish extends service life in exterior, high-humidity, and corrosive environments. It is packaged and sold individually, making it appropriate for replacement hardware, maintenance stock, or supplemental quantities on a project.

Key Features

• Thread size 5/8-11 UNC for compatibility with standard structural nuts and washers
• 5.5 inch length under head provides grip length suitable for thick structural connections
• Steel construction meeting ASTM A325 high-strength structural bolt specification
• Hot-dipped galvanized finish delivers corrosion resistance for exterior and industrial use
• Partially threaded shank concentrates clamping force and resists shear loads in bearing-type connections
• Sold as a single unit for maintenance, repair, and small-quantity needs

Compatibility

Designed as a high-strength structural hex head bolt per ASTM A325, compatible with 5/8-11 UNC heavy hex nuts and structural flat washers used in standard steel-to-steel bolted connections.

Installation Notes

Installation should be performed by qualified trades following AISC Specification for Structural Steel Buildings and applicable project specifications. Power down or de-energize adjacent systems before working in energized structural bays. Use calibrated torque wrenches or tension-control methods as required by the connection type and project engineer of record. Do not reuse A325 bolts that have been fully tensioned, as they are not rated for re-tensioning.
