  • Patent number: 4451190
    Abstract: Disclosed is a fastener assembly (10) and fastener (20) in which a post (11) includes a pair of recesses (14a,14b) for mating engagement with a pair of inwardly extending projections (32a,32b,42a,42b) on a nut-like fastener (20). The structure of the coating assembly (10) allows for sliding relative movement between the nut-like fastener (20) and the post (11) when the nut (20) and post (11) are in a first orientation, and when reoriented permits the harder projections (42a,42b,32a,32b) to cut into the post and thereby inhibit disengagement of the nut (20) from the post (11) until the first reorientation is reobtained.
