Hex Head Bolt 1/2-13 x 7 Grade 5

The Hex Head Bolt 1/2-13 x 7 Grade 5 from ALLSTAR PERFORMANCE is a heavy-duty fastener engineered for high-stress mechanical applications requiring superior tensile strength and reliability. This 1/2-13 inch thread bolt delivers Grade 5 performance—rated for significantly higher load capacity than standard hardware—making it the correct choice for motorsports assembly, off-road vehicle builds, equipment mounting, and any structural application where fastener failure is not an option.

Specification details matter in fastener selection. The 1/2-inch diameter with 13 threads-per-inch (coarse pitch) provides balanced clamp load and ease of installation without requiring specialized threading. The 7-inch length accommodates thick assemblies and layered components common in frame work, engine block reinforcement, and transmission mounting. Grade 5 steel construction delivers approximately 120,000 PSI minimum tensile strength—roughly 20% higher than Grade 2 hardware. Zinc oxide plating provides corrosion resistance suitable for indoor mechanical work and protected mounting environments, protecting against surface rust during storage and light duty exposure.

This fastener serves motorsports builders, fabricators, off-road recovery specialists, and equipment technicians who demand fastener integrity. The 3/4-inch hex head accepts standard socket and wrench tooling, enabling rapid installation and removal in field conditions. Individual units allow operators to stock precisely what's needed for specific assemblies without overbuying case quantities. Sold as a single bolt, this product works for prototype testing, repair scenarios, or supplementing existing fastener inventory.

Grade 5 fasteners occupy a middle position between standard commercial hardware and premium Grade 8 specifications. For most mechanical assemblies—engine bay work, driveline components, structural reinforcement—Grade 5 delivers the strength-to-cost balance that experienced builders depend on. Zinc plating is lighter than full galvanizing but adequate for temperature-stable indoor and protected outdoor use.
