The specification discloses a one-piece injection-molded screw hole plug fitting over a screw head to aesthetically close a screw hole. The element defining the screw hole and the top of the screw hole plug have nonplanar, but mating contours so that, the molding and plug define a generally continuous surface. Preferably the screw hole plug friction fits within the screw hole and over the screw head to retain the plug in position.

Why it's free to use
- Filed March 13, 1992 and granted April 26, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 13, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 13, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
