9/16-12 Stud 4.750 OAL Broached

The ARP 9/16-12 Stud 4.750 OAL Broached fastener is a precision-engineered chromoly component designed for high-strength threaded applications in performance engines, racing platforms, and critical industrial assemblies. This broached stud delivers the dimensional accuracy and material integrity required where standard fasteners cannot be trusted to maintain clamp load under extreme conditions.

Manufactured to ARP's exacting standards, this stud features a 9/16-12 thread specification, 4.750-inch overall length, and black oxide finish for corrosion resistance in harsh engine bay environments. The broached design ensures consistent thread geometry and eliminates the stress concentrations that can develop in rolled threads under cyclic loading. Chromoly material provides superior tensile strength compared to standard steel, making it the choice for applications where vibration, temperature cycling, and sustained clamping force demand reliability. At 0.31 lbs, the stud integrates seamlessly into weight-sensitive performance builds.

This fastener is engineered for engine builders, motorsports competitors, and restoration specialists who specify ARP fasteners for cylinder head clamping, intake manifold mounting, and other critical engine assembly points. The 9/16-12 thread size and 4.750-inch length align with proven engine block and head designs, delivering the precise clamp load characteristics needed for proper gasket sealing and structural integrity. Sold individually, allowing builders to replace one stud at a time or assemble complete fastener kits tailored to their specific application requirements.
