Datasheets(X)
The AMO® III frame screw has been developed by Würth and can be used for example for stress free spacing of windows and doors made of wood, plastic or wood/aluminium.
The screw is self-tapping, which means that the screw cuts its own thread in concrete, bricks or wood. In concrete and bricks, predrilling is necessary, but not in aerated concrete and wood.
