Value Collection HCI21000600G-010BX Hex Head Bolt Grade 2

Product Description

The VALUE COLLECTION HCI21000600G-010BX is a Grade 2 steel hex head bolt with a 1-8 UNC thread and a 6 inch length under head. It features a hot-dipped galvanized finish that provides corrosion resistance for exterior and exposed applications. The bolt is partially threaded, meaning a portion of the shank remains unthreaded to allow for shear load transfer in structural and mechanical assemblies. It conforms to ASTM A307 standards, making it a recognized option for general-purpose bolted connections in construction, equipment fabrication, and mechanical installations. Plumbers, electricians, HVAC technicians, and general contractors commonly use fasteners of this type when anchoring equipment, strut channels, or pipe supports.

This bolt is suited for a wide range of trade and light structural applications where ASTM A307 compliance is required. Typical uses include securing pipe hangers, equipment bases, duct supports, electrical panel supports, and structural framing members. The hot-dipped galvanized finish makes it appropriate for outdoor, damp, or corrosive environments where bare steel fasteners would be prone to rust. It is sold individually and is compatible with standard 1-8 UNC hex nuts and flat washers.

Key Features

• 1-8 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• 6 inch length under head for applications requiring extended grip length
• Hot-dipped galvanized finish for corrosion resistance in outdoor and damp environments
• Partially threaded shank allows shear load transfer across joint interfaces
• Grade 2 steel meets ASTM A307 for general-purpose structural and mechanical use
• Sold as a single unit with a minimum order quantity of 1

Compatibility

Designed for use with standard 1-8 UNC hex nuts, flat washers, and lock washers in general-purpose bolted assemblies requiring ASTM A307 Grade 2 compliance.

Installation Notes

Install using a standard hex wrench or impact driver fitted with the appropriate socket. Ensure mating nuts and washers are also galvanized or otherwise corrosion-rated when used in outdoor or wet locations to prevent galvanic incompatibility. Power down or de-energize any adjacent electrical equipment before working in confined mechanical spaces. Follow applicable codes such as the IBC or applicable mechanical codes for minimum bolt engagement and torque requirements on structural connections.
