ABSTRACT:
A pin and grommet assembly includes a push-pin and a grommet of unique construction which is capable of absorbing variations in the relative positions of a supporting panel and a mating panel to be attached caused by thermal expansion and contraction. A pair of diametrically opposed semicylindrical-shaped portions are disposed on the push-pin and cylindrical-shaped mating grooves are formed in the interior of the grommet for retaining freely floating the semicylindrical-shaped portions in the grommet so as to permit lateral sliding engagement between the opposed outer wall surfaces on the shorter sides of the main body portion of the grommet.
