fischer FAFS Screw for precision adjustments

fischer FAFS adjusting screws are problem-solvers for steplessly adjustable assembly of wooden constructions or frames.‎ The specialised combination of bit and setting tool turns the screw through the attachment part, ensuring it is flush with the surface.‎ The countersunk clip of the screw does not rotate during adjustment, ensuring the head retains its position in the attachment part.‎ The distance between the attachment part and the substrate can be infinitely and precisely adjusted thanks to the opposed rotational direction.‎ The adjusting screw is ideal for fastening and adjusting ceiling and wall substructures on wooden substrates.‎ Further info from manufacturer on FAFS fischer
