Title:
SPIRALLY RIDGED SELF-LOCKING DOWEL-TYPE FASTENER
Document Type and Number:
WIPO Patent Application WO/2020/083458
Kind Code:
A1
Abstract:
A dowel-type fastener is disclosed. The spirally ridged self-locking dowel-type fastener has an optimized shape, to achieve a less resistant and non-destructive penetration, a considerably stronger fastening interaction, and a higher axial withdrawal strength. Its functional lateral surface (5) comprises a plurality of parallel spiral ridges (7) defined by pairs of leading slopes (10) and trailing slopes (13). The leading slopes (10) are generally smooth surfaces, spanning between a channel bottom (11 ) and a smooth helix ridgeline (12), designed to slide the fastener into a penetrated receiving member (6). The trailing slopes (13) have a rough form designed to bite the receiving member {6} into a locked position.
