Value Collection 3GBM905C0012 Hex Bolt 5/16-18 3/4in Grade 2

Product Description

The VALUE COLLECTION 3GBM905C0012 is a fully threaded hex head bolt designed for general fastening applications in construction, mechanical assembly, and light structural work. It features a 5/16-18 UNC thread size with a 3/4-inch length under head, providing reliable clamping force in a compact form factor. The bolt is manufactured from Grade 2 steel with a hot-dipped galvanized finish, offering corrosion resistance suitable for both indoor and outdoor environments. The 1/2-inch hex drive is compatible with standard wrenches and sockets. This fastener conforms to ANSI/ASME B18.2.1 dimensional standards.

This bolt is suited for residential and light commercial applications where a corrosion-resistant, fully threaded fastener is required. Typical uses include framing connections, equipment mounting, plumbing fixture attachment, and general mechanical assembly. The hot-dipped galvanized coating makes it appropriate for applications with exposure to moisture or mild chemicals. Trade professionals in HVAC, plumbing, and electrical work commonly use Grade 2 hex bolts for bracket and equipment mounting tasks where high-strength alloy fasteners are not required.

Key Features

• 5/16-18 UNC thread for broad hardware compatibility
• Fully threaded along the 3/4-inch length under head for maximum thread engagement
• Grade 2 steel construction meets general-purpose structural fastening requirements
• Hot-dipped galvanized finish provides corrosion resistance for outdoor and wet environments
• 1/2-inch hex head fits standard wrenches and sockets
• Conforms to ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 dimensional standards

Compatibility

Designed as a standard UNC hex head bolt suitable for use with 5/16-18 threaded nuts, inserts, and tapped holes in steel, wood, and similar substrates where a Grade 2 galvanized fastener meets the application requirement.

Installation Notes

Installation typically requires a standard 1/2-inch wrench or socket driver. Confirm that the mating nut or tapped hole matches the 5/16-18 UNC thread specification before installation. Apply appropriate thread engagement depth per the relevant ANSI/ASME standard for the joint being assembled. Do not use impact tools at excessive torque settings, as Grade 2 fasteners are not rated for high-strength structural joints.
