Value Collection HCI20621300G6-001BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI20621300G6-001BX is a 5/8-11 UNC hex head bolt with a 13-inch length under head, manufactured from Grade 2 steel with a hot-dipped galvanized finish. Partially threaded along the shank, this fastener meets ASTM A307 standards, making it suitable for general structural and mechanical assembly applications where corrosion resistance is needed. Weighing approximately 1 pound, it is a heavy-duty fastener sized for use in applications that require a long grip length with a clean unthreaded shank section between the bearing surface and the threaded end.

This bolt is used in a wide range of construction, mechanical, and trade installations where 5/8-inch threaded fasteners are specified. Hot-dipped galvanized coating makes it well suited for outdoor, wet, or corrosive environments, including structural framing, equipment mounting, utility installations, and infrastructure applications. Tradespeople working in plumbing, electrical, HVAC, and general construction commonly specify ASTM A307 Grade 2 fasteners for non-critical structural connections.

Key Features

• 5/8-11 UNC thread size with 13-inch length under head for long-grip applications
• Partially threaded shank keeps the grip section smooth for precise clamping
• Hot-dipped galvanized finish provides enhanced corrosion resistance in outdoor and wet environments
• Meets ASTM A307 fastener standard for general-purpose structural use
• Grade 2 steel construction balances strength and workability for standard mechanical assemblies

Compatibility

Designed as a general-purpose hex head bolt compatible with standard 5/8-11 UNC threaded nuts, washers, and hardware conforming to inch-measurement fastener specifications.

Installation Notes

Install using a standard hex wrench or impact driver sized for a 5/8-inch hex head fastener. Ensure mating nuts and washers are rated for use with galvanized hardware to prevent galvanic compatibility issues. Follow applicable structural or mechanical codes when specifying fastener torque for the joint type. Always inspect the galvanized coating for damage before installation in corrosive environments.
