Title:
METHOD AND APPARATUS FOR FASTENING TOGETHER STRUCTURAL COMPONENTS
Document Type and Number:
WIPO Patent Application WO2004007858
Kind Code:
A3
Abstract:
A method and apparatus for fastening a first relatively soft structural component (350) such as a wood panel to a second relatively hard structural component (352) such as a steel angle iron using fasteners (8) each having a forward self-drilling portion, a rearward, self-tapping portion, and an outwardly projecting head. The fasteners are driven by a pneumatic rotary impact driver (2) and the method comprises rotatively driving each fastener so as to cause its self-drilling portion to drill a first hole through the wood panel and thereafter rotatively driving and impacting that fastener so as to cause its self-drilling portion to drill a second hole in the angle iron and its self-tapping portion to form a screw connection with the angle iron around the second hole.
