Abstract: A fastener assembly includes a body, a cup and a faceplate. The fastener assembly is a long thin shape for insertion into an opening in a substrate prior to actuation. Once inserted in the substrate, the fastener assembly may be actuated by the insertion of a bolt into a central aperture in the assembly and the tightening of the bolt against the cup. The actuation of the assembly causes the body of the assembly to fold at four points and to thereby secure the assembly to the substrate.

Abstract: A locking member has a first surface, a first mounting opening and a second mounting opening. Each first mounting opening and second mounting opening is dimensioned to receive the shank portion of a corresponding rotatable member therethrough so that a bottom surface of a head portion of the rotatable member faces toward the first surface of the locking member. A first extending member extends elastically relative to the first surface, wherein the first extending member is disposed in close proximity to the first mounting opening. When the rotatable member is in a mounting position in the first mounting opening, the first extending member contacts the head portion of the rotatable member to inhibit the rotatable member from rotating in a first direction, and the first extending member deflects elastically when the rotatable member rotates in a second direction opposite the first direction.

A projection extends from the compression ledge and a contact shoulder is formed at an intersection of the projection and the compression ledge. The shoulder has a thickness measured axially from the compression ledge and extends radially outward from the projection to the intersection of the shoulder and the compression ledge. A compressible sealing component encapsulates the exterior end surface of the head and partially overlaps an area entirely around the compression ledge. The compressible sealing component at the area of the compression ledge has an uncompressed axial thickness greater than the shoulder thickness measured from the compression ledge. A rotation preventer is formed on the projection and is configured to allow axial movement of the projection into a hole and to restrict rotation of the fastener when the projection extends into the hole.
