发明名称 SELF-DRILLING FASTENER FOR PLASTERBOARD WALL
摘要 An improved fastener mountable to a plasterboard wall from one side of the wall and used with a screw comprises a fastener body and a toggle clamp pivotable between an insertion position and a toggle position. The fastener has a drilling tip adapted to drill a hole of sufficient diameter to accommodate the fastener, except for a head, which is adapted to coact with a driving tool. In a first embodiment, the drilling tip is an integral part of the fastener body and extends axially beyond the toggle clamp in its insertion position. In a second embodiment, the drilling tip is an integral part of the toggle clamp and extends axially beyond the fastener body in the insertion position of the toggle clamp. In each embodiment, the fastener is self-drilling.
