 Detailed Description
These Proform wedge locking header bolts are permanently assembled with a pair of special washers. When the bolts are torqued to 28 ft.-lbs., 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. Because this simple wedge-locking method uses tension instead of friction, contact with oil actually facilitates the wedge effect. When changing headers, the Proform wedge locking header bolts can be loosened with a normal wrench, lubricated, and reused.
