ABSTRACT:
A quarter-turn fastener has a bolt having a head and a screw-threaded shank, and a retainer assembly threadably secured to the shank as a tight friction fit thereon. The retainer assembly has a pair of abutments for engagement with the rear of a support, through an aperture in which the retainer assembly locates in use. The retainer assembly includes at least one pair of stops for engagement with the sides of the aperture in the support or a corresponding aperture in a panel in which the fastener is mounted in use, to define the inoperative and operative positions of the retainer assembly. A compression spring is located in use between the retainer assembly and an opposed surface of the panel to retain the retainer assembly in its inoperative position under the action of friction, when the retainer assembly is disengaged from the support.
