ABSTRACT:
A locking ring for preventing inadvertent unfastening of threaded fasteners comprises a substantially cylindrical ring having a slot extending the entire width of the ring for allowing the ring to be easily compressed to fit into a counterbore that is slightly smaller than the uncompressed ring. The locking ring also comprises at least one protrusion on the outer surface of the ring that is capable of being inserted into an indentation in the counterbore when the ring is inserted in the counterbore. The locking ring is capable of having a threaded member disposed therethrough when the locking ring is disposed in the counterbore. The locking ring may also be crimped so as to engage the threaded fastener disposed therein so that the interconnection of the locking ring with the counterbore and threaded fastener prevents inadvertent unfastening of the threaded fastener.
