Bolt Kit - 12pt. (5) 7/16-20 x 3.000

The Bolt Kit - 12pt. (5) 7/16-20 x 3.000 from ARP is a precision fastener assembly engineered for demanding tactical, military, and high-performance automotive applications where reliability under extreme conditions is non-negotiable. This five-piece kit delivers the exact fastening solution required in mission-critical builds where component failure is not an option. Whether you're assembling engine blocks in precision rifle platforms, securing structural components in armor systems, or performing critical reassembly work in law enforcement or military equipment, ARP's reputation for uncompromising quality ensures every fastener meets exacting tolerances and performance standards.

Each bolt in this kit features a robust 12-point head design that distributes load evenly across the fastening surface, reducing stress concentration and preventing rounding common with 6-point alternatives under high-vibration or shock-load environments. The 7/16-inch diameter with 20 threads-per-inch (TPI) specification provides superior holding power in applications requiring sustained clamping force, while the 3-inch length accommodates deep-threaded applications without requiring extended studs or secondary fasteners. ARP's proprietary materials and manufacturing process yield fasteners that resist corrosion, maintain preload under thermal cycling, and deliver consistent performance across the operational temperature range encountered in tactical and military platforms.

Operators, gunsmiths, and armament specialists rely on ARP fastener kits for precision rifle builds, suppressor mounting assemblies, and critical structural reassembly where standard hardware would introduce unacceptable failure risk. The 7/16-20 x 3.000 specification is commonly employed in engine block assembly and high-stress mounting applications requiring thread engagement depth and load distribution superior to lighter fastener grades. This five-piece configuration suits replacement or initial build scenarios, with individual bolts available for supplemental purchases. Verify thread pitch compatibility with your specific application before installation; the 20 TPI specification is distinct from coarser alternatives and requires precise hole preparation for optimal results.
