Bolt Kit - 6pt. (5) 7/16-14 x 2.500

The ARP Bolt Kit – 6pt. (5) 7/16-14 x 2.500 is a precision fastener assembly designed for high-performance applications where reliability and repeatability are essential. This five-piece kit is ideal for professionals in motorsports, aerospace, and industrial assembly, providing the consistent clamping force and thread security needed for mission-critical builds.

Each bolt features a 6-point head geometry that distributes load evenly across the fastening interface, reducing the risk of rounding or stripping under torque. The 7/16-14 thread specification—7/16-inch diameter with 14 threads per inch—ensures precise tension control and repeatability across multiple assemblies. The 2.500-inch length accommodates deeper counterbores and stacked components commonly found in engine blocks and transmission housings.

Technicians and builders working on high-output engines, supercharger systems, or reinforced chassis components will find this kit invaluable for critical joint applications. ARP's rigorous quality control, including grain structure verification and hardness testing, ensures that each fastener meets aerospace and motorsport standards. The 6-point head design is compatible with standard 11/16-inch sockets, making it a versatile choice for various applications.
