Abstract: A lock nut assembly configured to couple to a threaded bolt includes a base nut having a bore with an angled inner wall defining and angled ramp portion, the base nut bore configured to receive the threaded bolt, and a lock nut having an angled outer wall defining a wedge portion. The lock nut is configured to threadably engage the threaded bolt such that the wedge portion is driven into the angled ramp portion, the angled inner wall is configured to force the wedge portion to exert a clamping force against the threaded bolt to lock the base nut in place.
