Bolt Kit - 6pt. (5) 3/8-16 x 3.000

The ARP Bolt Kit – 6pt. (5) 3/8-16 x 3.000 is a premium fastener set engineered for precision applications where chromoly strength and reliable clamping force are non-negotiable. Each of the five bolts in this kit features ARP's chromoly construction with black oxide finish, delivering corrosion resistance and consistent performance in demanding conditions. The 3/8-16 thread specification and 3-inch length make this fastener set suitable for engine builds, suspension work, and other high-stress assembly applications where OEM fasteners fall short of performance requirements.

Chromoly bolts offer superior tensile strength compared to standard steel fasteners, reducing the risk of failure under load cycling and vibration. The 3/8-inch hex head provides adequate leverage for torque application while the 3-inch length accommodates deeper bore holes and thicker material stacks. Black oxide coating resists surface corrosion without adding significant bulk, critical for applications exposed to moisture or salt environments. The six-point head design ensures positive grip and reduces the chance of rounding during installation—a key advantage when working with precision tools or in tight tolerances.

This fastener set is specified for engine builders, fabricators, and technicians assembling systems where fastener failure can trigger catastrophic consequences. Whether securing cylinder heads, mounting critical brackets, or anchoring suspension geometry, ARP bolts deliver the clamping consistency and fatigue resistance that separate production-quality assemblies from field failures. The universal design allows cross-platform application, making this kit a practical addition to any shop's fastener inventory. Set of five bolts ensures adequate spares for the primary assembly plus contingency stock.
