Value Collection 3GBM908C0108 Hex Head Bolt 1/2-13

Product Description

The VALUE COLLECTION 3GBM908C0108 is a Grade 2 steel hex head bolt with a 1/2-13 UNC thread and a 1-1/2 inch length under head. It carries a hot-dipped galvanized finish for corrosion resistance in outdoor and wet-environment applications. The shank is partially threaded, which provides a smooth grip section for better clamping in structural and mechanical assemblies. This bolt conforms to ANSI/ASME B18.2.1 dimensional standards. It is driven with a 3/4 inch hex wrench or socket and is sized for standard 1/2 inch fastener applications. Installers in HVAC, plumbing, electrical, and general mechanical trades commonly stock this bolt for equipment mounting, unistrut work, and structural connections.

This bolt is suited for light-to-medium structural and mechanical fastening tasks in both residential and commercial settings. The hot-dipped galvanized coating makes it appropriate for exterior installations, wet mechanical rooms, rooftop equipment mounting, and other environments where bare steel would corrode prematurely. The partially threaded design is preferred where a full-shank bearing surface is needed, such as bolting through flanges, brackets, or equipment pads. It is sold in a minimum order quantity of 50 pieces, making it practical for stocking or larger installation projects.

Key Features

• 1/2-13 UNC thread for compatibility with standard 1/2 inch nuts and tapped holes
• 1-1/2 inch length under head for use in moderate-thickness assemblies
• Grade 2 steel construction provides adequate strength for general-duty fastening
• Hot-dipped galvanized finish resists corrosion in outdoor and wet environments
• Partially threaded shank delivers a smooth grip section for improved clamping force
• Meets ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 dimensional standards

Compatibility

Designed as an OEM-style and aftermarket replacement fastener for standard 1/2-13 UNC threaded applications in equipment mounting, structural framing, and mechanical assemblies across trade industries.

Installation Notes

Installation is performed with a 3/4 inch socket or open-end wrench. Always verify thread engagement depth and ensure the mating nut or tapped hole meets the same UNC thread standard before torquing. Power down or de-energize any equipment before replacing or installing fasteners on live assemblies. Follow applicable mechanical and structural codes for minimum thread engagement and fastener grade requirements.
