ABSTRACT:
A castellated nut has 8 castellation slots in the outer wall. A circular locking insert has 25 long locking tabs radiating outwardly from the perimeter, an axle-engaging tongue protruding inwardly, and 9 smaller holding tabs which fit into an interior circular nut groove. All 25 locking tabs are bent at 90 degrees up from the circular locking insert and the axle slot-engaging tongue is bent down at 90 degrees. The locking insert is pressed into the nut and the small holding tabs are bent into the interior circular groove in the nut. The axle-engaging tongue is aligned with the axle shaft groove. The locking axle nut is threaded onto the axle shaft and tightened with the axle slot-engaging tongue sliding in the axle groove. One of the 25 locking tabs is bent into one of the 8 castellation slots.
