Value Collection HCI30620500N-010BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI30620500N-010BX is a 5/8-11 UNC hex head bolt designed for structural and general industrial fastening applications. Manufactured from A325 steel with a bright uncoated finish, this bolt measures 5 inches in length under the head and features partial threading along the shank. The Grade A325 designation meets ASTM A325 structural bolt standards, making it suitable for steel-to-steel connections where high-strength fasteners are required. Licensed electricians, ironworkers, millwrights, and mechanical contractors routinely specify A325 hardware for structural connections, equipment mounting, and heavy-duty assemblies.

This bolt is suited for structural steel connections, steel frame construction, equipment anchorage, and heavy mechanical assemblies where ASTM A325 compliance is required. The partially threaded shank provides a bearing surface in the grip area, which is standard practice for structural bolted connections. The 5/8-11 UNC thread form is one of the most common heavy-duty inch-series thread sizes across industrial, construction, and mechanical trades.

Key Features

• Grade A325 steel construction meets ASTM A325 structural bolt standard
• 5/8-11 UNC thread form for compatibility with standard heavy-duty inch-series nuts and hardware
• Partial threading provides a clean bearing surface along the shank in the grip zone
• Bright uncoated finish — suitable for painted, galvanized, or coated assembly environments
• 5-inch length under head accommodates multi-layer structural stack-ups
• Weighs 0.63 pounds per unit

Compatibility

Designed for use with standard 5/8-11 UNC heavy hex nuts and washers in structural bolted connections meeting ASTM A325 fastener requirements.

Installation Notes

Installation of structural A325 bolts should be performed by qualified ironworkers or mechanical contractors following AISC and RCSC specifications for structural bolting. Bolts must be installed with appropriate hardened washers under the turned element as required by the connection design. Tightening method — snug-tight, turn-of-nut, or direct tension indicator — must be specified by the engineer of record. Never reuse A325 bolts that have been fully tensioned in a slip-critical connection.
