Abstract: A locknut (12) has an L-shaped slider (18) formed of a washer-like piece (19) held above a nut (13) by a contiguous spring element (20) spot-welded to the nut. The spring causes the washer to press against a bolt (33) or stud with locking torque when the locknut is secured thereon, and to rest away from the nut when not adjacent a bolt or stud. While the locknut is being tightened or loosened, a wrench (29) forces the spring against the nut so the washer surrounds a bolt or stud without contacting it. A skirt (43), of straight or downwardly-curved cantilevers (46, 46a) may be disposed on an annulus secured to a surface of the nut opposite the washer, for additional locking torque.

Abstract: An anti-theft fastener with locking feature includes a nut, a nut casing, a lock casing and a lock. An engaging ball of the lock casing gets embedded in an engaging groove of the nut casing. The lock and its' casing are positioned inside the nut casing.

The positioning ball is no longer embedded inside a positioning engaging passage of the nut casing, thereby preventing the nut casing from driving the nut except idling. Under locked condition, the fastener is unable to be mounted. To dismount the fastener requires turning the lock with a key until the engaging ball falls into a curved groove of the lock and exits the engaging groove. The positioning ball is pushed outward and embedded inside the positioning engaging passage, thereby unfastening the screw element.
