Specification

The self-drilling screw with up to 50% time savings when fastening wood to metal sub-structures

AW drive system:

Better mounting output thanks to fatigue-free screwing in; the required contact pressure for transmission of the torques is considerably lower

Even force distribution prevents damage to the surface-protection coating and therefore ensures better resistance to corrosion

Notice

Wing-piasta screws must be appropriately tested for usability for each application case. 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)

∅ 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.

Instructions

How it works

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
