Abstract
A screw grommet comprises a shank inserted into a mounting hole in a workpiece and a flange formed at one end of the shank that is larger than the mounting hole in the workpiece. A cavity is formed in the flange and the shank into which a tapping screw can be screwed after insertion through a hole in a member to be mounted on the workpiece. The shank has a rectangular cross-section appropriate for a rectangular cross-section mounting hole in the workpiece. Both the flange and a portion of the shank are divided by a plurality of axial slits. Protrusions are formed diagonally on the outer periphery of the shank separated axially from the flange by about the thickness of the workpiece. The screw grommet is able to obtain high retention force with respect to a workpiece without rotating together with a turned screw.
