The ARP 1/4-20 12-point nuts (10-pack) are precision-engineered chromoly fasteners designed for high-strength mechanical assemblies where reliability and corrosion resistance are non-negotiable. These 1/4-20 threaded nuts feature a 5/16-inch 12-point head geometry and black oxide finish, making them ideal for engine builds, suspension systems, automotive restoration, and industrial fastening applications where superior holding power and durability are required.
The 12-point head design provides better wrench engagement compared to standard 6-point geometry, reducing the risk of rounding during installation and removal. Chromoly material offers significantly higher tensile strength than standard steel, making these nuts suitable for vibration-prone environments and applications subject to cyclic loading. The black oxide coating delivers corrosion protection while maintaining a professional appearance across engine bays, chassis work, and exposed mechanical systems. Each nut conforms to standard 1/4-20 threading specifications, ensuring compatibility with matching bolts and studs across industrial and automotive markets.
This 10-pack format serves engine builders, automotive technicians, restoration shops, and fabricators who assemble custom or high-performance mechanical systems. The set is practical for complete engine overhauls, bracket installations, suspension modifications, and any fastening scenario where chromoly strength and 12-point accessibility matter. Whether securing engine components, fuel system fittings, or structural mounts, these nuts provide the tensile performance and corrosion resistance needed for long-term reliability.
ARP fasteners are recognized in the performance automotive and motorsports community for consistent quality and engineering precision, making these 1/4-20 12-point nuts a trusted choice for builds where fastener integrity directly impacts system performance and longevity.
