| titleOfInvention | SELF-DRILLING SCREW FOR FASTENING WOOD PARTS ON SHEETS |
| abstract | The self-drilling screw secures a wooden component to sheet-metal, being particularly for rafters to a roof base structure. It has a drill tip (5) and a spanner or screwdriver head (7) at opposite ends of the shank (3), with a parallel supporting thread (6) in between. A washer (10) guided on the shank bears against a face (8) on the head and on which there are radial ribs (8'). These fit in mating radial grooves (120') in the washer, and/or the latter has outside milling protrusions (10'). ADVANTAGE - Forms firm joint while reducing risk of overtightening. |
