Steel, Ruspert^®-coated (grey)

Corrosion protection

Approx. 500 hrs. no base metal corrosion in accordance with DIN EN ISO 9227 — NSS

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

Notice

Wing-pias must be appropriately tested for usability for each application case. Only install using application tools with depth stop and claw coupling.

The maximum attachment thickness l_B is calculated as follows: Wood thickness and substructure thickness l_U

Drilling screws may only be used where dampness is not to be expected. For connection elements with a construction permit, the permit, and in particular Part 2 "Special regulations", must always be observed.

Application area

For use with soft woods

Instructions

• 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
