For mounting wooden frames.

The frame screw is used for the tension-free, spaced installation of window and door frames made of wood in different building materials (e.g. pumice, block concrete, perforated brick, solid stone) as well as for wooden constructions with square timber. The frame screw with cheese head should be used for countersunk mounting in wooden profiles. When mounting aluminium and plastic profiles, it is recommended to use a frame screw with a flat head.

1.) Drill hole through the frame into the substrate
2.) Screw in the frame screw
The frame screw is inserted via the push-through installation method. The full thread of the screw prevents the window or door frame from being tightened against the substrate during installation and ensures tension-free, long-lasting fastening of the frame.
