ABSTRACT:
An improved fastening device is disclosed for securing within an aperture of a workpiece. The invention comprises a longitudinally extending body member for insertion within the aperture of the workpiece. The fastening device includes a locking shoulder secured to the longitudinally extending body member such that the shoulder is spaced relative to a surface of the workpiece by resilient material. A groove is disposed in the body member for receiving the resilient material for coacting between the body member and the workpiece for reducing undesired movement therebetween. In an alternative embodiment of the invention a fastening device is disclosed for the reception therein of a thermo-setting material, the device being secured within a plurality of apertures defined by a multi-layered workpiece. The fastening device includes a first lamina member which defines a first plurality of transverse bores each of which are aligned with an aperture of the plurality of apertures. A plurality of elongate members each having a first and a second end are secured with the first end of each of the elongate members being disposed within one of the plurality of bores such that there is a clearance between the workpiece and each of the elongate members. The clearance is filled with the thermo-setting material so that there is no contact between the workpiece and the elongate members.
