ABSTRACT There is described a substantially cylindrical screw grommet capable of accepting a threaded fastener driven obliquely with respect to the axis of the grommet, the exterior surface of the grommet being formed with axial rows of spaced barbs, the rows being separated by flutes, and the grommet being further formed with a bore which has a first cylindrical portion intermediate the length of the grommet, a first tapered portion connecting the first cylindrical portion to a second cylindrical portion of smaller diameter, and a second tapered portion of the bore diverging from the second cylindrical portion and terminating at one end of the grommet. One of the embodiments of the invention described is capable of accepting a single threaded fastener driven into one end of the grommet obliquely with respect to the grommet axis, and a further embodiment is described which is capable of accepting two threaded fasteners, one being driven into each end of the grommet, the axes of both the threaded fasteners being oriented obliquely with respect to the axis of the grommet. The grommet may include a diametral weakened section so that the grommet expands radially when a threaded fastener is driven there into.
