Hex Head Bolt 5/8-11 x 4 Grade 5 5pk

The Hex Head Bolt 5/8-11 x 4 Grade 5 5pk from ALLSTAR PERFORMANCE is a precision fastener engineered for high-load applications where structural integrity is non-negotiable. Whether you're assembling tactical equipment, reinforcing vehicle mounts, or securing critical components in field operations, Grade 5 bolts deliver the reliability demanded in law enforcement and military environments. This five-piece set provides redundancy and replacement capacity, ensuring you maintain operational readiness without downtime.

Grade 5 bolts are manufactured to withstand tensile stresses up to 120,000 PSI, offering superior holding power compared to commercial-grade fasteners. The 5/8-inch diameter with 11 threads-per-inch (UNC) specification provides balanced clamp force and vibration resistance essential for dynamic tactical platforms. The 4-inch length accommodates thick brackets, rail systems, and load-bearing structural connections without protruding excessively. The hex head design allows secure engagement with standard wrenches and sockets, enabling field-expedient installation and removal without specialized tools.

Professionals in tactical vehicle outfitting, equipment mounting, and armorer work will recognize the value of stocking Grade 5 fasteners in common sizes. The 5pk quantity suits maintenance programs, allows for parallel assembly tasks, and provides spares for emergency field repairs. Compatibility spans universal applications—from weapon system accessories and ballistic protection frameworks to equipment racks and load-bearing infrastructure. These bolts perform reliably across temperature extremes and corrosive environments when paired with appropriate washers and locking hardware.
