A FASTENER CLIP FOR USE IN SUPPLYING FASTENERS TO A FASTENER DRIVING TOOL
Document Type and Number:
WIPO Patent Application WO2004007977
Kind Code:
A3
Abstract:
A clip of fasteners for use in attaching a structural panel to a metal substrate comprises a plastic strip with openings characterized by inwardly-extending ribs for gripping and supporting fasteners that comprise a forward self-drilling portion, a rearward self-tapping thread portion and cutting blade means formed integral with the self-drilling portion. Each fastener has a head with a top surface adapted for driving engagement by a driver tool for rotatively driving the fastener, and a tapered surface having a plurality of circumferentially spaced cutting edges that function to cut away the ribs supporting the fastener as the fastener is rotatively driven through the structural panel to secure the panel to the substrate and create a countersink in the structural panel.
