Countless fastening jobs require stand-off installation, such as substructures made of wood used to clad walls and ceilings. fischer says its new FAFS adjusting screw with an ETA approval is ideal when stand-off installation is required.

The new adjusting screw FAFS features a clever clip on the head of the screw as well as many other technical ingenuities. Its special operating principle makes positioning and aligning fixtures such as substructure battens quicker, simpler and more precise. 

Any unevenness in the anchor substrate can easily be levelled out and straightened. The unique thread of the PowerFast II version provides a quick bite and is easy to screw in. The special shape of its clip prevents it from rotating during adjustment so that the screw head retains its flush position in the attachment part without protruding. The FAFS can be disassembled at any time, if required. A thread is located on the outer part of the clip, allowing it to be unscrewed. 

The FAFS is suitable for push through installation and is very user friendly. Simply place the setting tool onto the bit and screw in the adjusting screw until it sits flush with the surface of the fixture. Now everything is in place for the infinite adjustment of the attachment part. The component distance can be adjusted with the bit without the setting tool and by altering the rotational direction. The clip remains in its position in the fixture while doing so.

Pre-drilling with a diameter of 6mm is recommended for wood slats with a strength of less than 30mm or hard wood as well as installation close to an edge. Applications in masonry are possible with the fischer DuoPower 6x50 or UX 6x50 plugs, which also requires pre-drilling with a diameter of 6mm. The current range includes four FAFS variants in measurements of 5mm x 80mm, 5mm x 90mm, 5mm x 100mm and 5mm x 120mm, each with a TX25 drive. The corresponding setting tool with a suitable bit is also available through fischer.
