Locking plates engage a keyway in a shaft or adapter sleeve and are attached to the side face of the nut by two bolts secured with locking wire. A locking plate consists of a plate, two hexagonal head bolts with drilled heads and lock wire to secure them.Position the locking plate in the keyway. Tighten the nut further, if required, to align the holes in the plate with the holes on the side face of the nut, making sure that the plate maintains its position in the keyway. Screw both bolts into the side face of the lock nut and tighten them.
