ABSTRACT:
An anti-rotation locking device for threaded fasteners which secure rotating parts subject to vibration, shock and the like. The device comprises a strap member and one or more retainer members. The strap member is positioned under the fasteners and the retainer members each have a toothed opening which is installed over the matching wrenching surface of the fastener. Each retainer member also has an arcuate slot which is positioned above an arcuate tang on the strap member. The tang is lifted, passed through the slot, bent about the bottom of the slot and folded back over the top surface of the retainer member to thereby restrain the loosening of the fastener.
