The screw grommet 1 comprises a flange 2 and a shank 3 extending from the flange. The shank is provided with flexible legs 7 extending from the end of the shank towards the flange and outwardly from the shank. The shank has a screw insertion hole 13 into which a tapping screw is screwed to prevent the legs from being bent radially inward towards the shank so that the screw grommet is fixed to the workpiece by means of the legs and the flange. The inner portion of the legs is provided with a threaded section turned by screwing in the tapping screw. The flange 2 is integrated with a tubular fastening torque bearing section 18 extending in the direction opposite the shank 3. The fastening torque bearing section is formed with a screw insertion hole having a diameter smaller than the outside diameter of the tapping screw so as to receive the tapping screw.
A screw grommet, wherein the grommet is equipped with a flange and a shank extending from the flange, wherein the shank is hollow and inserted into an attachment hole in a workpiece, wherein the shank has flexible legs extending towards the flange from the end of the shank and extending radially outward from the shank with the end towards the flange being the free end, wherein a threaded through-hole is formed in the flange and shank for receiving a tapping screw, wherein screwing the tapping screw into the threaded through-hole prevents warping of the free end of the legs towards the inside radially, wherein the flange and the legs securely in contact with the edge of the attachment hole in the workpiece fix the grommet to the workpiece, wherein a threaded section is formed on the inside section of the free end of the legs for receiving the tapping screw and extending towards the inside so the diameter of the threaded through-hole becomes smaller than the outer diameter of the tapping screw, wherein a tube-shaped fastening torque bearing section extending opposite the shank is integrated with the flange, wherein a threaded through-hole is formed in the fastening torque bearing section with a diameter smaller than the outside diameter of the tapping screw for receiving the tapping screw, and wherein the fastening torque from screwing in the tapping screw is born by the fastening torque bearing section outside the threaded section of the legs.
Screw grommet wherein the grommet is equipped with a flange and a shank extending from the flange, wherein the shank is hollow and inserted into an attachment hole in a workpiece, wherein the shank has flexible legs extending towards the flange from the end of the shank and extending radially outward from the shank with the end towards the flange being the free end, wherein a threaded through-hole is formed in the flange and shank for receiving a tapping screw, wherein screwing the tapping screw into the threaded through-hole prevents warping of the free end of the legs towards the inside radially, wherein the flange and the legs securely in contact with the edge of the attachment hole in the workpiece fix the grommet to the workpiece, wherein a threaded section is formed on the inside section of the free end of the legs for receiving the tapping screw and extending towards the inside so the diameter of the threaded through-hole becomes smaller than the outer diameter of the tapping screw, and wherein the sections of the legs other than the threaded section are thin and extendable so as to draw the free end closer to the flange when the tapping screw is screwed in and fastened.
