Processing of hardwood and softwood by countersunk head with milling ribs
- Only install using application tools with a depth stop and claw coupling
- Drilling screws must be processed with a suitable drill driver (e.g. cordless drill driver with depth stop)
- The use of impact screwdrivers is not permitted
- Drilling screws must be attached perpendicular to the surface of the component
Wing-tip drilling screws must be appropriately tested for usability for each application case.
- Wooden floors on steel substructures
- Especially for mounting on IPE steel beams (with parallel inner surfaces of the flanges)
- Steel quality of the substructure up to a yield strength of 460MPa (tensile strength Rm 520-670 MPa)
