ABSTRACT:
A nut cap and assembly therewith is provided. The capped nut assembly is made up of a nut body and a cap. The nut body has an elongated internally threaded member formed with polygonal side walls extending from a collar member at the inner end toward the outer end, and the cap has a hollow shell with an end wall closing one end and being open at an opposite end. The cap is sleeved over said nut body with its side wall surrounding the polygonal side walls and its closed end overlies the outer end of the nut body, and the open end of the cap has a radially inwardly flared resilient lip portion that attaches to the collar member in a snap fitting relationship. The outer end of the nut body has an engagement member protruding therefrom, and the inside surface of the hollow shell has a ramping member at a location that it is adapted to strike the engagement member whenever the cap is rotated about the nut body such that the ramping member biases the resilient lip portion in a direction to release its holding force on the collar portion.
