ABSTRACT:
A screw grommet has a flange and a leg extending therefrom and has cantilever-like engagement projections extending tangentially with respect to the outer periphery of the leg. A panel can be held clamped between the flange and engagement projections. When inserting the leg through an opening in the panel, the engagement projections are easily flexed to facilitate the insertion.
