A locking device with two keys spaced approximately 180 degrees center to center and protruding from the seating surface of the ring. When installed the keys mate with companion keyways in the external threads of screw thread inserts, locked-in studs, or similar type items, and cut through sufficient threads of the parent material tapped hole to provide a positive lock between the threaded bodies.
