ABSTRACT:
A brittle thermoplastic molded cylindrical hollow hole seal has a top wall and a depending side wall. An annular external rib snap fits to an annular groove in a hole side wall to secure the seal in place. Axially extending angularly shaped in cross section grooves are on the side wall interior and spaced axially extending slots pass through the side wall. The top wall internally has an eight point star shaped set of ridges and troughs whose points terminate at the side wall forming the interior grooves. Reflective aluminum flakes are in the material to provide a spotty finish. The slots, grooves, ridges and troughs form weakening regions causing the seal to shatter in response to an applied local pressure, for example, exerted by a screw driver for use with a screw plugged by the seal. The spotty appearance is difficult to hide when the seal is broken.
