Value Collection 3GBM908C0308 Hex Head Bolt 1/2-13

Product Description

The VALUE COLLECTION 3GBM908C0308 is a Grade 2 steel hex head bolt with a 1/2-13 UNC thread and a 3-1/2 inch length under head. It features a hot-dipped galvanized finish that provides corrosion resistance for outdoor and high-moisture applications. The bolt is partially threaded, conforming to ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 dimensional standards. A 3/4 inch hex drive makes it compatible with standard wrenches and impact drivers. This fastener is used by plumbers, pipefitters, HVAC installers, electricians, and general contractors wherever a reliable, corrosion-resistant structural bolt is required.

This bolt is suited for structural connections, equipment mounting, flange assembly, pipe support bracketing, and general mechanical fastening in residential and commercial trade applications. The hot-dipped galvanized coating makes it appropriate for exterior installations, rooftop equipment mounting, underground utility work, and other environments with exposure to moisture or the elements. Its partially threaded shank provides a bearing surface that resists lateral shear loads, which is a common requirement in structural and mechanical assemblies.

Key Features

• 1/2-13 UNC thread for compatibility with standard nuts and tapped components
• Hot-dipped galvanized finish for corrosion resistance in exterior and high-moisture environments
• Partially threaded shank provides a smooth bearing section that resists shear loads
• 3/4 inch hex drive works with standard wrenches and impact tools
• Meets ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 dimensional standards
• Grade 2 steel construction suitable for general-purpose structural and mechanical fastening

Compatibility

Designed as a standard 1/2-13 UNC hex head bolt for use with any ANSI/ASME B18.2.2-compliant hex nut or fitting accepting a 1/2 inch coarse-thread fastener.

Installation Notes

Install using a 3/4 inch combination wrench, box wrench, or impact driver socket. Verify that mating nuts and washers are also galvanized or otherwise rated for the same corrosion environment to prevent galvanic incompatibility. Follow applicable code requirements under the IBC, IFGC, or NEC when using fasteners in structural, gas-system support, or electrical equipment mounting applications. Always de-energize or depressurize systems before servicing connected equipment.
