Storable in ORSY ® Method of functioning 1. Drilling out of the wood by the wings prevents forced advancement of the screw 2. Drilling of the core hole in the sub- structure. Breakage of the wings upon contact with the metal 3. First few threads of the screw cut the thread, into which the screw then turns Note: Wing pias ® have to be appropriately tested for usability before each application. Use only application equipment with depth stop and claw clutch. Drilling screws may only be used where dampness is not to be expected. For fasteners with a construction approval, the approval, and in particular Part 2 "Special regulations", must always be observed. For dia. 3.9 / 4.2 / 4.8 mm General construction permit Z-14.4-634 For use of wood and gypsum material boards and cementitious mineral construction material boards with thin- walled steel proles.
