ABSTRACT:
An anti-rotation locking assembly for releasably fastening automotive exhaust pipes and exhaust manifolds to an engine block is disclosed comprising a threaded bolt with hex-wrenching recess and a hyperbolic locking plate with hex-stud which fits into the wrenching recess of the bolt and is attached thereto by cotter pin or Q clip. The locking plate has a contour which mates with said exhaust pipe and thereby prevents the bolt from working loose due to vibration of the engine.
