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 stud designed for high-performance engine builds and critical fastening applications. This product is ideal for mechanics and automotive enthusiasts who are undertaking serious modifications, such as stroker builds or forced induction setups, where reliability is paramount.

Constructed from premium alloy steel and heat-treated to exacting standards, this stud offers superior tensile strength and fatigue resistance compared to standard fasteners. Its broached design ensures uniform internal geometry, allowing for dependable torque-to-yield performance during repeated assembly and disassembly cycles. The 12mm x 1.75 thread pitch ensures compatibility with common metric applications, while the 6.320-inch length accommodates deeper boss holes and longer engagement zones.

This ARP stud is particularly beneficial for builders working on LS, small-block Chevy, Ford modular, or import engine modifications, where the risks of OEM fastener stretch and bolt creep can compromise reliability. The broached internal profile guarantees concentricity, delivering predictable clamp load that translates to consistent head gasket sealing and improved combustion chamber integrity under boost or high RPM conditions.
