Hex Head Bolt 1/2-13 x 5 Grade 5

The ALLSTAR PERFORMANCE Hex Head Bolt 1/2-13 x 5 Grade 5 is a heavy-duty fastener engineered for demanding mechanical and structural applications. This 1/2-13 threaded bolt measures 5 inches in length with a 3/4-inch hex head, offering the strength and holding power required in high-stress assembly and repair work. Grade 5 steel construction with zinc oxide plating delivers corrosion resistance and reliable performance in field conditions where fastener failure is not an option.

Grade 5 bolts occupy the middle ground of the hardness spectrum, providing superior tensile strength compared to Grade 2 fasteners while maintaining machinability and resistance to brittle fracture under shock load. The 1/2-13 thread pitch—coarse and widely compatible—ensures quick engagement and robust clamping force across standard American mechanical assemblies. At 0.32 pounds, this individual bolt integrates seamlessly into larger projects without adding unnecessary weight, while zinc oxide coating extends service life in mildly corrosive environments typical of field operations and outdoor equipment repair.

This fastener serves mechanics, technicians, equipment specialists, and field operators who demand reliability in critical assembly work. Common applications include frame repair, structural reinforcement, suspension assembly, winch and recovery equipment mounting, and general-purpose machinery fastening. The 5-inch length accommodates thick material stacks and through-bolt configurations where shear strength and long-term clamp retention are essential.
