The M12 head stud set offered by us is the result of many years of experience that we have gained while designing and building motorsport engines. Thanks to the commitment of our engineers and access to advanced materials, we are pleased to offer unsurpassed quality at an affordable price. Pins easily withstand a tightening torque of 120 Nm (and more). An indispensable element with every turbo conversion and also in the case of broken M10 threads on aluminum M52 and M54 engines. Beware of other "similar" solutions in the M10 class at a similar price, which flow in a short time at 1.2 bar. Only the diameter and material far exceeding class 12.9 will behave as it should.
