A fastener assembly includes a lock nut secured to an object, and a screw engaged through the other objects and threaded to the lock nut for securing the objects together. The lock nut includes a peripheral flap extended from one end of a tubular member and engaged with the object, and one or more ribs engaged into the object, for preventing the lock nut from rotating relative to the objects. The screw may thus solidly engage with the lock nut. The other end of the lock nut is machined radially outward to engage with the object, and to secure the ribs in the object.
