Value Collection 3GBM908C1200 Hex Head Bolt 1/2-13 12 in

Product Description

The VALUE COLLECTION 3GBM908C1200 is a Grade 2 galvanized steel hex head bolt with a 1/2-13 UNC thread and a 12-inch length under head. It is partially threaded, making it suited for applications where a smooth shank is needed between clamped surfaces. The hot-dipped galvanized finish provides corrosion resistance for outdoor and exposed installations. The 3/4-inch hex drive is compatible with standard wrenches and impact drivers. This bolt meets ANSI/ASME B18.2.1 dimensional standards and is installed by maintenance technicians, pipefitters, HVAC mechanics, and general contractors working on structural and mechanical assemblies.

This bolt is used in a wide range of trade and industrial applications including HVAC equipment mounting, mechanical room structural connections, pipe support systems, and general fabrication. The partially threaded shank helps resist shear loads in bolted joints. Its galvanized finish makes it suitable for outdoor, wet, or moderately corrosive environments such as rooftop equipment pads, exterior support structures, and utility enclosures. Grade 2 classification indicates a low-carbon steel with moderate tensile strength appropriate for general-purpose fastening rather than high-stress structural joints.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard nuts and tapped holes
• 12-inch length under head provides fastening reach for thick assemblies or stacked materials
• Partially threaded shank improves shear resistance in bolted connections
• Hot-dipped galvanized finish for corrosion resistance in outdoor and wet environments
• Meets ANSI/ASME B18.2.1 dimensional standards for consistent fitment
• Grade 2 low-carbon steel for general-purpose structural and mechanical fastening

Compatibility

Designed as a general-purpose hex head bolt for use with standard 1/2-13 UNC nuts and hardware in structural, mechanical, and HVAC mounting applications.

Installation Notes

Install using a 3/4-inch wrench or socket. Always power down or de-energize associated equipment before securing bolted connections on mechanical or electrical enclosures. Use appropriate flat washers and lock washers or lock nuts to prevent loosening from vibration. Follow applicable building codes and equipment manufacturer specifications for fastener torque and joint design requirements.
