Value Collection HCI20620500G-025BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI20620500G-025BX is a Grade 2 steel hex head bolt with a 5/8-11 UNC thread and a 5-inch length under head. It carries a hot-dipped galvanized finish that provides corrosion resistance for outdoor and moisture-exposed installations. The bolt is partially threaded, following ASTM A307 standards for general-purpose structural and mechanical fastening applications. At approximately 1 pound, it is suited for medium-duty assemblies where a standard hex drive and UNC thread form are required. Plumbers, HVAC technicians, electricians, and general contractors reach for this type of fastener when securing equipment frames, structural supports, and pipe hangers.

This bolt is appropriate for use in residential and commercial construction, mechanical rooms, equipment pads, and utility installations. Its hot-dipped galvanized coating makes it a practical choice for exterior applications, treated lumber contact, and environments with moderate moisture exposure. The partial thread configuration leaves a smooth shank near the bolt head, which is common in through-bolting applications where shear strength along the shank is a factor. Sold individually, it can be sourced in the quantity needed for a specific job without excess.

Key Features

• 5/8-11 UNC thread for compatibility with standard hex nuts and threaded inserts
• 5-inch length under head provides reach for thick structural members or stacked components
• Hot-dipped galvanized finish for corrosion resistance in outdoor and damp environments
• Partial threading retains a smooth shank for applications requiring shear resistance
• Meets ASTM A307 standard for general-purpose low-carbon steel externally threaded fasteners
• Grade 2 steel suitable for non-critical structural and mechanical fastening

Compatibility

Designed as a general-purpose replacement or service fastener for applications requiring a 5/8-11 UNC hex head bolt in Grade 2 galvanized steel per ASTM A307.

Installation Notes

Installation is performed by the applicable licensed trade or general contractor depending on the assembly being fastened. Always shut down and de-energize any equipment before fastening or removing hardware in mechanical or electrical systems. Use calibrated torque tools when torque values are specified by the equipment manufacturer or relevant code. Refer to applicable building codes, NEC, IFGC, or IPC requirements for fastener specifications in structural or utility installations.
