A fastening device includes a fastener, a lock washer, and a lock nut. The fastener has a head portion, a threaded body portion, and a longitudinally extending flat section formed in the threaded body portion. The lock washer has an upper surface and a circumferential surface extending therefrom. The circumferential surface includes an array of radially-extending ratchet teeth. The lock washer also has an aperture with a flat inner surface configured to engage the flat section of the fastener and rotationally fix the lock washer. The lock nut has an upper surface and a peripheral outer surface extending therefrom and defining an axially-extending recessed portion. The upper surface includes an integrally-formed pawl arm having a tapered inner surface defining a tapered slot between the pawl arm and the lock nut in axial alignment with the recessed portion. The pawl arm includes a pawl tooth for engagement with the array of ratchet teeth.
