Abstract

A self-lock and self-retained structural fastener assembly (10) is disclosed. The fastener assembly (10) comprises a plate member (12) having an opening (14) and a pair of receivers (16, 18). A retainer (20) that has a threaded opening (22), a pair of oppositely disposed spring fingers (24, 26) and a pair of oppositely disposed hooks (28, 30) is coupled to the plate member (12) by lockably inserting the hooks (28, 30) within the receivers (16, 18) of the plate member (12) to form a fastener housing (32). A stud (34) is rotatably positioned within the fastener housing (32). The stud (34) has a boss (36) and first and second threaded sections (38, 40) extending in opposite directions from the boss (36). The stud (34) has an uninstalled position wherein the first threaded section (38) is threadably engaged with the threaded opening (22) of the retainer (20). The stud (34) also has an installed position wherein the second threaded section (40) extends outwardly through the opening (14) of the plate member (12) and the boss (36) is locked between the spring fingers (24, 26).
