Hex Head Bolt 1/2-13 x 3 Grade 5 5pk

The Hex Head Bolt 1/2-13 x 3 Grade 5 5pk from ALLSTAR PERFORMANCE is a precision fastener engineered for high-stress applications in tactical, military, and industrial environments. This five-piece set delivers the reliable threaded fastening required in equipment assembly, mounting systems, and structural builds where failure is not an option. Grade 5 bolts are the standard choice for professionals who demand consistent performance under demanding field conditions and repetitive stress cycles.

Each bolt features a 1/2-inch diameter with 13 threads per inch (1/2-13 specification), a 3-inch length, and a 3/4-inch hex head for secure wrench engagement and positive torque application. Grade 5 steel construction with zinc oxide plating provides superior tensile strength—approximately 120,000 psi—and corrosion resistance essential for field deployment and outdoor gear assembly. The hex head design ensures proper load distribution and prevents stripping when used with standard or impact wrenches, making installation and removal straightforward without specialized tools.

Tactical professionals, armorers, and equipment technicians rely on Grade 5 fasteners for weapon mounting, platform stabilization, and load-bearing component assembly. The zinc oxide finish resists atmospheric corrosion while maintaining dimensional accuracy for precision fit in tight tolerances. This 5pk format is ideal for maintenance kits, field repairs, and prototype builds where redundant fasteners ensure mission readiness. Compatible with any standard 1/2-13 threaded hole, these bolts integrate seamlessly into AR platforms, support systems, and custom gear configurations requiring NATO-standard specification compliance.
