Value Collection 3GBM905C0108 Hex Head Bolt 5/16-18

Product Description

The VALUE COLLECTION 3GBM905C0108 is a 5/16-18 UNC hex head bolt designed for general fastening applications across construction, mechanical assembly, and maintenance work. Manufactured from Grade 2 steel with a hot-dipped galvanized finish, this bolt provides corrosion resistance suitable for outdoor and moderately exposed environments. The fastener measures 1-1/2 inches in length under the head and features partial threading, which maintains clamping force on unthreaded shanks in grip applications. The 1/2-inch hex drive accepts standard wrenches and sockets. This bolt meets ANSI/ASME B18.2.1 dimensional standards and is a practical choice for high-volume fastening jobs where galvanized protection and reliable Grade 2 strength are required.

This bolt is suited for residential and light commercial construction, structural framing connections, equipment mounting, and general maintenance installations where a 5/16-18 UNC threaded fastener with galvanized corrosion protection is specified. The partial threading configuration is appropriate when the unthreaded shank needs to pass cleanly through a clearance hole before engaging a nut or tapped receiver. Contractors, millwrights, and maintenance technicians commonly specify Grade 2 galvanized hex bolts for wood-to-metal connections, fence and railing hardware, and utility structure assembly.

Installation Notes

Installation is performed with a standard 1/2-inch wrench or socket, by a qualified tradesperson or mechanic per applicable project specifications. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Do not exceed the rated torque range for Grade 2 fasteners as defined by applicable mechanical or structural specifications for the application. When used in structural connections, verify that fastener grade and finish meet local building code or project engineer requirements.
