Value Collection 3GBM908C0104 Hex Head Bolt 1/2-13

Product Description

The VALUE COLLECTION 3GBM908C0104 is a fully threaded hex head bolt designed for general fastening applications in construction, mechanical assembly, and structural work. Sized at 1/2-13 UNC thread with a 1-1/4 inch length under head, this bolt is manufactured from Grade 2 steel with a hot dipped galvanized finish that provides corrosion resistance in outdoor and moisture-exposed installations. The 3/4 inch hex drive accommodates standard hex wrenches and impact sockets. Compliance with ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 ensures dimensional consistency across the lot. Tradespeople and maintenance crews working with galvanized steel assemblies, framing hardware, or equipment mounting will find this a straightforward, code-compliant fastener choice.

This bolt is suited for residential and light commercial applications where a UNC fully threaded fastener is required. Common install scenarios include equipment base mounting, framing connections, mechanical supports, and general structural assembly. The hot dipped galvanized coating makes it appropriate for exterior use, pressure-treated lumber contact, and other environments where bare steel would corrode prematurely. Minimum order quantity is 50 pieces, making this bolt well suited for contractors and shops maintaining fastener stock.

Key Features

• Grade 2 steel construction meets general-purpose structural fastener requirements
• Hot dipped galvanized finish for corrosion resistance in exterior and high-moisture environments
• 3/4 inch hex drive compatible with standard wrenches and impact sockets
• Conforms to ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 dimensional standards

Compatibility

Designed as an OEM-style replacement or new-installation fastener for any application requiring a 1/2-13 UNC fully threaded hex head bolt with a 1-1/4 inch length under head in Grade 2 galvanized steel.

Installation Notes

Installation is performed by carpenters, millwrights, pipefitters, or general maintenance tradespeople depending on the application. Always use the correct 3/4 inch hex wrench or socket and ensure mating threads are clean and free of debris before assembly. Follow applicable codes such as the IBC or OSHA structural fastener guidelines for torque and inspection requirements. Do not mix galvanized fasteners with incompatible dissimilar metals in assemblies where galvanic corrosion is a concern.
