Abstract
A fastener, such as a housing, for mounting to a structure, such as a panel, that has an aperture formed therethrough. The fastener includes a shank member and an annular nut member that is configured to align coaxially with the shank member. The shank member is inserted through aperture in the structure and the nut member is placed on the shank member. Teeth on the radially outwardly facing surface of the shank member engage a pawl, such as one or more teeth, on the radially inwardly facing surface of the nut member to lock the nut member to the shank member. Removal of the nut member is effected by rotating the nut member to disengage the pawl from the teeth, thereby permitting longitudinal displacement of the nut member off of the shank member.
