Abstract
A screw grommet of synthetic resin having an enlarged head part adapted for abutment against the surface of a mounting panel, a shank adapted for engagement with an oblong fitting hole bored in the mounting panel, a pair of integral shoulders extending from opposite walls of the shank, and a pair of integral elastic arms extending at a prescribed angle from the other pair of opposite walls of the shank. The pair of elastic arms and the pair of engaging shoulders engage with the corresponding edges of the oblong fitting hole in the mounting panel. The screw grommets are always retained in the correct posture in the oblong fitting holes and absorb errors in manufacture or fabrication. The screw grommets are also capable of absorbing variations in the relative positions of the fitting holes in the panel and the through-holes in a part to be attached caused by expansion or contraction due to a change in temperature.
