12mm x 1.75 Stud 6.320 AOL - Broached

The ARP 12mm x 1.75 Stud 6.320 AOL Broached fastener is a precision-engineered chromoly stud designed for high-strength threaded applications in demanding mechanical assemblies. This 6.32-inch-long broached stud delivers the dimensional consistency and load-bearing capability required in motorsports, industrial machinery, and performance engine builds where standard fasteners cannot provide adequate clamping force or reliability.

Manufactured from chromoly steel with a black oxide finish, this ARP stud offers superior corrosion resistance compared to bare steel while maintaining the material's excellent tensile strength and fatigue resistance. The broached design ensures a precise thread fit and eliminates the runout and inconsistencies common in rolled-thread fasteners, critical for applications where bolt preload accuracy directly affects component longevity and performance. The 12mm diameter with 1.75 fine-pitch threading provides a larger engagement surface and finer clamping increments than coarse-pitch alternatives, enabling more precise load distribution across joint surfaces.

This stud is engineered for engine block, cylinder head, and structural assemblies in high-performance applications where vibration resistance and consistent preload are non-negotiable. Typical users include engine builders, race teams, machine shops, and automotive professionals working on forced-induction systems, competition engines, or critical industrial equipment. Sold individually, each ARP 12mm x 1.75 Broached Stud allows builders to replace damaged fasteners or construct custom assemblies with confidence in consistent dimensions and reliable performance.
