  • Enclosed plastic screw grommet
    Patent number: 4971500
    Abstract: An enclosed plastic screw grommet includes a head flange and a shank portion. The head flange is provided with four radially extending U-shaped slots so as to permit flexing upon insertion into a panel, thereby reducing the force needed. The shank portion includes two sets of opposed ramps formed on its outer surface and which are disposed in an offset relationship with respect to each other to thereby accommodate a variety of panel thicknesses.
