SBC S/S Complete Engine Fastener Kit 12pt.

The SBC S/S Complete Engine Fastener Kit 12pt. from ARP is a professional-grade fastener solution designed specifically for small-block Chevrolet builders who require reliability under extreme conditions. This complete kit is perfect for assembling street engines, drag strip competitors, or high-revving road course platforms, eliminating the hassle of sourcing individual fasteners from multiple suppliers.

ARP has established a reputation for precision-manufactured fasteners that can withstand combustion pressures, thermal cycling, and sustained high RPM loads that standard fasteners cannot handle. The 12-point head design provides superior grip geometry compared to standard 6-point fasteners, minimizing the risk of rounding during installation and removal. This design also allows for better wrench engagement, enabling more precise torque application during engine assembly.

This complete fastener kit is ideal for engine builders, performance shops, and serious enthusiasts who are rebuilding or upgrading their engines. Each fastener is calibrated to meet OEM and ARP specifications, ensuring proper clamping loads that prevent gasket failure and internal component movement, making it a reliable choice for high-performance applications.
