Value Collection HCI30620375N-015BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI30620375N-015BX is a 5/8-11 hex head bolt manufactured from steel to ASTM A325 structural bolt standards. It measures 3-3/4 inches in length under the head and features partial threading along the shank. The bright, uncoated finish leaves the steel bare, making it suitable for applications where coating or galvanizing is not required. This fastener is installed by ironworkers, structural contractors, and mechanical tradespeople working on steel-to-steel connections where high-strength performance is specified by design engineers or project drawings.

This bolt is used in structural steel connections in commercial, industrial, and heavy construction applications. ASTM A325 bolts are commonly specified in steel frame construction, bridge work, and heavy equipment assemblies where high-strength fasteners are required by code or engineering specification. The 5/8-11 UNC thread size and 3-3/4 inch under-head length suit medium-thickness steel connection points. Partial threading provides a bearing-length shank that resists shear loads at the bolt-hole interface, which is a key characteristic in structural applications.

Key Features

• ASTM A325 structural steel bolt standard for high-strength applications
• 5/8-11 UNC thread size, inch measurement system
• 3-3/4 inches length under head for medium-depth structural connections
• Partially threaded shank provides a bearing surface to resist shear loads
• Bright, uncoated finish — no additional coating treatment
• Steel construction meeting A325 material grade requirements

Compatibility

Designed as an ASTM A325 structural hex head bolt for use in steel-to-steel connections where 5/8-11 UNC high-strength fasteners are specified.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural contractors following AISC and RCSC bolt specification guidelines. Torque or tension requirements are determined by project engineering documents and must not be assumed from generic values. Inspect mating steel surfaces and hole alignment before fastener installation. Use appropriate impact or torque tooling rated for structural fastener work.
