Abstract: A truck bumper dock extension with a flip step configurable for use on a truck body to provide a functional bumper and a dock extension for loading and unloading at an elevated truck-dock and with the flip step configurable for use on the truck body for loading and unloading at an un-elevated surface, such as for home delivery. A walking ramp and stowing compartment is secured by the flip step for secure transport and removable access to a walking ramp.

Abstract: A fastener has a head with an exterior end surface and a compression ledge. 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.
