Value Collection 3GBM908C0400 Hex Head Bolt 1/2-13 4in

Product Description

The VALUE COLLECTION 3GBM908C0400 is a 1/2-13 UNC hex head bolt manufactured from Grade 2 steel with a hot-dipped galvanized finish. It measures 4 inches under the head and features partial threading, making it suited for through-bolt and clamping applications where a smooth shank is required in the grip zone. The 3/4-inch hex drive fits standard sockets and wrenches. Conforming to ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 dimensional standards, this bolt delivers consistent geometry and predictable mechanical performance in general-purpose structural and mechanical assembly work.

This bolt is appropriate for a wide range of general-purpose fastening applications in construction, equipment assembly, HVAC equipment mounting, plumbing support structures, and light structural work. The hot-dipped galvanized coating provides corrosion resistance in outdoor, humid, or moderately corrosive environments. It is commonly used by contractors, maintenance technicians, and trade professionals who need a reliable, code-referenced fastener for both interior and exterior installations. Minimum order quantity is 25 pieces; package quantity is 1.

Installation Notes

Installation is typically performed by general contractors, maintenance technicians, or licensed tradespeople using standard hand or power tools fitted with a 3/4-inch socket or wrench. Always use a properly rated nut and washer rated for Grade 2 fasteners. Consult applicable building codes and engineering specifications for torque and load requirements before installation. Do not use hot-dipped galvanized bolts in contact with stainless steel or aluminum in highly corrosive environments without consulting a materials engineer.
