Value Collection HCI30620400N-015BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI30620400N-015BX is a 5/8-11 UNC hex head bolt rated to structural Grade A325 and manufactured from uncoated steel. With a 4-inch length under head and partial threading, this fastener is built for structural steel connections where high clamping force and controlled thread engagement are required. The bright, uncoated finish means no coating to interfere with contact surfaces in slip-critical or bearing-type connections. Ironworkers, structural steel erectors, and millwrights commonly specify this bolt configuration in heavy-duty bolted assemblies governed by structural fastener standards.

This bolt is suited for structural steel framing, beam-to-column connections, base plate assemblies, and similar applications where ASTM A325 specification fasteners are called out on engineering drawings or project specifications. Partial threading preserves a smooth shank section in the grip zone, which is standard practice for structural bolted joints where load transfer occurs through the shank rather than the threaded portion. This bolt is sold individually.

Key Features

• Grade A325 steel meets ASTM A325 structural bolt specification
• 5/8-11 UNC thread size for standard structural hardware compatibility
• 4-inch length under head with partial threading for proper shank grip length
• Bright uncoated finish — no coating buildup at faying surfaces
• Hex head drive for standard impact wrenches and torque wrenches
• Inch-system dimensions throughout

Compatibility

Designed as a structural replacement or new-installation fastener for bolted steel connections specifying 5/8-11 UNC ASTM A325 hex head bolts with a 4-inch length under head.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural steel erectors in accordance with AISC and RCSC specification requirements. Power off or de-energize any adjacent equipment before working in confined steel assemblies. Use a calibrated torque wrench or tension-control method as required by the applicable structural specification — do not estimate snug-tight by feel alone on A325 connections. Inspect bolt, nut, and washer assembly for proper grade markings before installation.
