AbstractA fastener assembly to be used in the construction of semi-trailers consisting of a first fastener having a head and a shank, a mating second fastener, and a plurality of radially spaced projecting barbs formed on the shank. The barbs, which may also be spaced axially on the shank, engage in a hole for receiving the first fastener to prevent rotation and removal of the first fastener. The first fastener may also be provided with an encapsulating cover with two sealing points on its underside to seal the fastener to a surface through which the fastener is inserted.
