Proform Parts Exhaust Header Bolt

Exhaust Header Bolt; Universal; 3/8 - 16 Inch Thread Size; 1 Inch Length; Locking Bolt; Hex Head; Black Oxide; Steel; With Wedge Locking Washers; Set Of 16

MPN: 66756

Each PROFORM® Grade 8 Header Bolt is permanently assembled with a pair of special washers. When the bolt is torqued to 28+ Foot-Pounds, the washers’ super-hardened external teeth bite into and grip the bottom of the bolt head and the top surface of the header. After being self-locked in this manner, any bolt-loosening rotation is blocked by a wedge-locking action created by the washers’ interfacing, matching cams. It’s an uphill climb: vibration that might ordinarily loosen the bolt actually increases the wedge-locking tension, securing the bolt even more. Because this simple wedge-locking 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.
