- Hardened C1 (not stainless steel!)
- RUSPERT® coated (silver)
- Countersunk milling head for use with hard and softwoods
- AW® drive for optimum power transmission and conservation of corrosion protection
Advantages in comparison to traditional drilling screws made of case-hardened steel
- For use with steel sub-structures with a strength of up to 700 N/mm2
- Faster cutting speeds possible
- The drill tip is strong enough for use with reinforced steel substructures
- The wing pias® of nominal dia. 6.3 mm, can be used in steel sub-structures made of A2 stainless steel up to 4 mm thick
- Wing-pias® screws must be appropriately tested for usability for each application case. Only install using application tools with a depth stop and claw coupling. *Wood thickness and surface thickness lu = max. attachment length lB
- 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
Drilling screws may only be used where dampness is not to be expected. For fasteners with a construction permit, the permit, and in particular Part 2 "Special regulations", must always be observed.
- 1. Force feeding of the screw is prevented by the wings drilling out the wood
- 2. The core hole is drilled into the substructure. The wings break off upon contact with the metal
- 3. The first few turns of the screw cut the thread, the remainder of the screw then screws into the thread
