ABSTRACT:
A plastic resin hole plug to fill a hole in a flat thin panel comprises a one-piece unitary injection-molded plastic member having a top dome closure wall whose bottom surface has a flat ledge which rests on the panel and an undercut ring. The plug has a tubular shank portion which extends from the top closure wall portion and whose outer face retains the plug in the hole. The shank's outer face has a first circumferential band canted inwardly and a second circumferential band joined thereto which is canted outwardly. At least one, and preferably two, side flats are formed on the shank portion, which flats flex inward when the plug is inserted into the hole.
