Description
Each PROFORM Grade 8 Header Bolt is permanently assembled with a pair of special washers When the bolt is torqued to 28 ftlbs the washers superhardened external teeth bite into and grip the bottom of the bolt head and the top surface of the header After being selflocked in this manner any boltloosening rotation is blocked by a wedgelocking action created by the washers interfacing matching cams Its an uphill climb vibration that might ordinarily loosen the bolt actually increases the wedgelocking tension securing the bolt even more Because this simple wedgelocking method uses tension instead of friction contact with oil actually facilitates the wedge effect When changing headers PROFORM Header Bolts can be untightened with a normal wrench lubricated and reused Sold as a set
