Hex Head Bolt 7/16-20 x 2-1/2 Grade 5 5pk

The Allstar Performance Hex Head Bolt 7/16-20 x 2-1/2 Grade 5 5-pack is a professional-grade fastening solution engineered for high-stress mechanical assembly and repair work. These Grade 5 steel bolts deliver the tensile strength and reliability demanded by operators, technicians, and builders working on performance equipment, off-road recovery systems, and structural assemblies where fastener failure is not an option.

Each bolt features a 7/16-inch diameter with a 20 threads-per-inch pitch and a 2.5-inch length, topped with a 5/8-inch hex head for firm wrench engagement and minimal cam-out risk. The Grade 5 classification guarantees a minimum tensile strength of 120,000 PSI, substantially higher than standard Grade 2 bolts, making these fasteners suitable for vibration-prone and load-bearing applications. The zinc oxide coating provides baseline corrosion resistance in dry and moderate-humidity environments, though users in marine or salt-air settings should consider periodic inspection or upgrade to stainless alternatives.

This five-pack serves technicians assembling engine blocks, transmission components, suspension mounts, winch systems, and equipment racks where specification-grade fasteners prevent catastrophic failure. The 7/16-20 thread pitch is common across automotive, powersports, and industrial equipment, making this fastener pack a practical stock item for shops, garages, and field kits. Cross-reference the Grade 5 rating against your specific load requirements; for critical safety-critical assemblies, confirm fastener selection against original equipment specifications.
