9/16-12 Stud 4.750 OAL Broached

The ARP 9/16-12 Stud 4.750 OAL Broached fastener is a precision-engineered component designed for serious engine builders and automotive technicians who demand reliability in high-stress applications. This stud serves as a critical clamping element in engine assembly, cylinder head fastening, and transmission mounting scenarios where standard bolts may not withstand extreme pressures and vibrations.

ARP's broached design on this 9/16-inch diameter stud provides superior clamping consistency compared to conventional rolled-thread fasteners, eliminating stress concentration points that can lead to fatigue failure. The 4.750-inch overall length accommodates thick-deck blocks and custom gasket stacks common in modern performance builds, while the 9/16-12 UNC thread size ensures optimal engagement and load distribution across critical fastening zones.

Professional engine builders, machine shops, and dedicated enthusiasts will benefit from the consistent tensile strength and elastic recovery provided by ARP's proprietary alloy and controlled heat-treat process. This stud is an essential component for ensuring cylinder head sealing integrity and block longevity in various engine configurations.
