Abstract: A generally inverted “T” shaped, resiliently self locking, integral sportboard fastener is adapted to be received in a countersunk aperture formed in a sportboard such as a snowboard, ski, boogie board, skateboard or any other board which supports a person and has one or more structures attached thereto. The fastener comprises a noncircular base portion to be received within a countersink defined in the sportboard. The base and the countersink comprise two parallel sides and two opposite concentric arcs forming two opposite ends. A generally cylindrical integral ferrule portion extends upwardly from the base, through a bore defined in the sportboard, concentric with the countersink. The ferrule defines internal threads to receive a screw to secure a binding or other fixture to the sportboard. An internal annulus portion is defined at the juncture of the base and ferrule. A generally circular, preferably nylon, resilient insert ring is disposed within the annulus.
