Description

• Bimetal (A2 stainless steel/drilling tip made of case hardened steel)
• RUSPERT^® coated (silver)
• With self-tapping thread
• Countersunk milling head for use with soft woods

AW drive system:

• Enhanced torque transmission
• Longer life
• Optimum centring
• Better mounting output thanks to fatigue-free screwing in; the required contact pressure for transmission of the torques is considerably lower
• Largest possible contact surface of bit in screw drive
• Even force distribution prevents damage to the surface-protection coating and therefore ensures better resistance to corrosion

Instructions

How it works

• Force feeding of the screw is prevented by the wings drilling out the wood
• The core hole is drilled into the substructure. The wings break off upon contact with the metal
• The first few turns of the screw cut the thread, the remainder of the screw then screws into the thread

Notice

Wing-piastas must be appropriately tested for usability for each application case. Only install using equipment with depth stop and claw coupling. ∅ 3.9/4.2/4.8 mm)

For use with wood and gypsum material boards and cement-bound mineral construction material boards with thin-walled steel profiles.
