S/S Bolt Kit - 6pt. (5) 3/8-24 x 2.750

The S/S Bolt Kit - 6pt. (5) 3/8-24 x 2.750 from ARP is a critical fastening solution for engine builders, performance shops, and serious automotive enthusiasts undertaking high-stress engine modifications. These stainless steel bolts are engineered to secure components that demand superior clamping force and corrosion resistance—think cylinder heads, intake manifolds, or custom bracket assemblies on turbocharged and naturally aspirated builds. When you're investing thousands in engine work, using OEM-grade or inferior fasteners is a false economy; ARP bolts deliver the reliability your modifications deserve.

This kit contains five 3/8-24 bolts, each measuring 2.750 inches in length with a six-point head design that distributes load evenly and reduces the risk of stripping—a significant advantage over conventional fasteners. The 3/8-24 thread pitch is a common specification for precision engine applications, offering fine granularity for accurate torque control and micro-adjustments critical to engine sealing and component alignment. Constructed from stainless steel, these bolts resist oxidation and corrosion far better than chrome-plated alternatives, ensuring longevity even in harsh underhood environments or exposed engine bay configurations. The six-point geometry also provides superior grip when using a socket wrench, minimizing slippage during installation and torque application—essential when working to tight tolerances.

Professional engine builders, race teams, and DIY mechanics restoring or modifying high-performance engines rely on ARP fasteners for their proven track record under extreme conditions—from street turbo builds to sustained high-RPM track duty. The 2.750-inch length and 3/8-24 specification make these bolts suitable for a wide range of automotive applications where standard fasteners fall short. Always consult your engine rebuild manual or technical documentation to confirm bolt hole depth and required torque specs; proper installation with a calibrated torque wrench ensures maximum clamp load and component security.
