Value Collection 3GBM904C0408 Hex Bolt 1/4-20 4.5in Grade 2

Product Description

The VALUE COLLECTION 3GBM904C0408 is a Grade 2 steel hex head bolt with a 1/4-20 UNC thread and a 4-1/2 inch length under the head. It features a hot-dipped galvanized finish for corrosion resistance in outdoor and exposed applications. The bolt is partially threaded with a 7/16 inch hex drive and conforms to ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 dimensional standards. This fastener is suited for general-purpose structural and mechanical assembly work and is commonly installed by HVAC technicians, plumbers, electricians, and general tradespeople requiring a reliable, code-conforming bolt in standard inch sizing.

This bolt is well suited for light-to-medium duty fastening tasks in residential and commercial trade applications. The partially threaded shank provides a bearing surface useful for bolted joints where shear load is a factor. The hot-dipped galvanized coating makes it appropriate for outdoor installations, equipment pads, mechanical rooms with moisture exposure, and other environments where bare steel would corrode prematurely. It is sold in minimum order quantities of 100 units, making it practical for stocking on service vehicles or in shop inventory.

Key Features

• 1/4-20 UNC thread for compatibility with standard inch-series nuts and tapped holes

• Hot-dipped galvanized finish resists corrosion in wet and outdoor environments
• 7/16 inch hex drive fits standard wrenches and sockets
• Meets ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 dimensional standards

Compatibility

Designed as an OEM-style replacement and general-use fastener compatible with any standard 1/4-20 UNC threaded hole or nut in inch-series mechanical and structural assemblies.

Installation Notes

Installation is performed by hand with a standard 7/16 inch open-end, box, or socket wrench. Always power down or de-energize any equipment before accessing fastener locations near electrical or mechanical components. Verify thread engagement and inspect galvanized coating for damage before installation in corrosive environments. Follow applicable codes and equipment manufacturer torque guidelines for the specific joint being assembled.
