InlinePRO – K20/K24 M-Series Head Stud Kit

Our K20/24 M-series M11 Extreme Duty head studs are made from the highest quality American steel that have gone through rigorous testing and treatment.¬†These are not prone to hydrogen embrittlement like the L19/H11 material and it can be handled without worrying about failures. We use a true beam design all the way through the length of the stud (it’s not necked-down or undercut like others) resulting in better clamping force and torque values. “Only settle for the Best!”
