Value Collection HCI30620600N-015BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI30620600N-015BX is a partially threaded hex head bolt designed for structural and heavy-duty fastening applications. Built to ASTM A325 standards, this bolt features a 5/8-11 UNC thread size and a 6-inch length under head. It is manufactured from uncoated steel, delivering the strength grade required for structural steel connections. Licensed contractors, ironworkers, and experienced tradespeople install these bolts in high-load assemblies where ASTM-rated hardware is specified by engineers or project drawings. The bright, uncoated finish leaves the steel surface bare, making it suitable for applications where coating-free contact is required or where field-applied coatings will be used.

This bolt is suited for structural steel connections in commercial and industrial construction, including beam-to-column connections, base plates, and heavy equipment mounting. The 5/8-11 thread size is a common specification in steel fabrication and erection work. Partial threading concentrates the full shank through the grip length of the joint, which is a standard requirement in high-strength structural bolt assemblies governed by AISC and related structural specifications.

Key Features

• ASTM A325 rated for high-strength structural fastening applications
• 5/8-11 UNC thread size with partial threading for full shank grip length
• 6-inch length under head accommodates thick material stacks and structural connections
• Bright, uncoated steel finish — no coating interference with torque-tension relationships
• Hex head drive style for standard impact wrenches and torque wrenches
• Sold individually — single-piece packaging for job-site flexibility

Compatibility

Designed as a high-strength structural replacement bolt conforming to ASTM A325 specifications, compatible with standard 5/8-11 UNC threaded nuts and structural steel assemblies requiring Grade A325 fasteners.

Installation Notes

Installation should be performed by qualified ironworkers, structural mechanics, or licensed contractors following applicable project specifications and AISC structural bolting requirements. Before installation, verify that mating nuts and washers meet the required ASTM specification for the joint design. Snug-tight or pretensioned installation methods must be applied as specified by the engineer of record — never substitute installation method without engineering approval. Use calibrated torque wrenches or approved tensioning equipment appropriate for 5/8-inch diameter high-strength bolts.
