Our Honda S2000 F20C F22C M-series M12 Extreme Duty head studs are made from the Highest Grade Premium American Alloy that have gone through rigorous heat treatment and testing. With a minimum tensile strength of 230kpsi, these are not prone to hydrogen embrittlement like the L19/H11 material and can be handled without worrying about failures. We use a True-beam design all the way through the length of the stud resulting in better clamping force and torque values (it's not necked-down or undercut like others). "Only settle for the Best!"
The kit includes: Studs, nuts, washers, lube, and instructions.
