Value Collection 3GBM905C0100 Hex Bolt 5/16-18 Grade 2

Product Description

The VALUE COLLECTION 3GBM905C0100 is a 5/16-18 UNC hex head bolt designed for general-purpose fastening applications in construction, mechanical assembly, and trade installations. Manufactured from Grade 2 steel with a hot-dipped galvanized finish, this bolt offers corrosion resistance suitable for both indoor and outdoor environments. The partially threaded shank measures 1 inch in length under the head and accepts a 1/2-inch hex wrench or socket. It conforms to ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 dimensional standards. This bolt is sold in a minimum order quantity of 100 units, making it appropriate for contractors and tradespeople working in volume.

This bolt is suited for light- to medium-duty fastening in residential and commercial construction, HVAC equipment mounting, plumbing support brackets, electrical panel work, and general structural assembly. The hot-dipped galvanized coating makes it a practical choice for applications with moderate moisture exposure. Electricians, plumbers, HVAC technicians, and general contractors commonly stock this size for everyday field use.

Installation Notes

Installation is performed using a 1/2-inch socket or open-end wrench. Always ensure the mating nut or tapped hole is the same thread standard (UNC) to avoid cross-threading. When installing in applications subject to vibration, a lock washer or thread-locking insert is recommended per project specifications. Follow applicable building codes and equipment manufacturer torque guidelines when fastening structural or load-bearing connections.
