Abstract
A downhole tool includes a fastening assembly securing one component to another component. The fastening assembly may include a threaded fastener located in an aperture of one component and a locking mechanism located in a cavity proximate the aperture. The threaded fastener may include a flange including mutually spaced holes located circumferentially within an outer periphery of the flange. The locking mechanism may include a spring and a dowel member. The locking mechanism may be positioned within a hole of the flange and may be configured to retain the threaded fastener in a fixed position relative to one component. Methods include using a depressor ring including teeth corresponding to the holes of the flange to depress the locking mechanism into the cavity while tightening the threaded fastener.
