ABSTRACT A removable reusable nut lock system (10) of the locking cap type for positively selectively removably retaining a standard nut (12) on the externally threaded end of a shaft (14) is provided. The lock nut assembly comprises an internally threaded bore (22) provided in the end of an externally threaded shaft having internal threads (24) of an opposite hand as the external threads (16) on the shaft. A locking cup member (26) is provided or slipping over the outer periphery of the nut for rotation therewith and the locking cup member is provided with a flange (32) having a plurality of ramp type ratchet teeth (38) on the outer periphery thereof. A locking cap member (28) is provided having an externally threaded stud (50) fixed thereto and a plurality of locking fingers (58, 60) extending radially outwardly and downwardly therefrom. The resilient locking fingers are designed to ratchet over the ratchet teeth of the locking cup upon tightening of the locking cap and will resist rotation of the nut member and locking cup in the removal direction of rotation of the nut relative to the externally threaded shaft.
