The respective versions of fischer’s full and partial threaded screws (Power-Full and Power-Fast) are particularly suitable for load-bearing wood structures, reinforcements and renovations, for wooden frame construction, outdoor areas, fastening rooftop insulation systems and much more. The product range provides the right screw type for every application in terms of diameter, length, head type, drive, thread, coating, material strength and other criteria – all with an assessment (ETA). Their clever designs make them easier to install while enabling gap-free and splinter-free fastenings close to the edge.
The Power-Fast group includes high-performance wood and chipboard screws with a partial thread, which allows them to be screwed in close to the edge without splitting. They are approved for soft and solid wood and are available in a stainless steel version especially for the outdoors. The Power-Full family specialises in challenging connections and reinforcing load-bearing wood structures. Thanks to their full thread, the wood screws transfer acting forces such as on main and secondary beam connections, false beam edges, shear tension bracings or shear connections. Any wood and steel-plate wood connection can be carried out with the versatile fischer Power-Fast and Power-Full screws.
fischer’s PowerFast II chipboard screw provides added benefits with its broad range of applications, including any wood on wood or wood on metal connections as well as in fischer’s plastic plugs with verified loads. PowerFast II guarantees good load-bearing capacity and makes installation quicker due to its fast bite and short screw-in time. Short edge distances and axial spacing are also possible without causing the workpiece to split. The Power-Fast II’s clever geometry with a specially developed screw tip prevents tears to surfaces.
New FAFS adjusting screw
Countless fastening jobs require stand-off installation, such as substructures made of wood used to clad walls and ceilings. The new FAFS adjusting screw with a European Technical Approval (ETA) is ideal for applications such as these. The PowerFast II version enables infinitely adjustable stand-off installation.
The FAFS features a clever clip on the head of the screw as well as many other technical ingenuities for this purpose. 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 screw 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, enabling 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 ready for the infinite adjustment of the attachment part. The component distance can be infinitely adjusted with the bit without an additional 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 6 mm is recommended for wood slats with a strength of less than 30 mm when installed close to the edge. The guidelines of ETA-19/0175 should be observed for approved applications. The product can be used in masonry with the fischer DuoPower 6x50 or UX 6x50 plugs, which also requires pre-drilling with a diameter of 6 mm. The current range includes four FAFS variants in measurements of 5x80 mm, 5x90 mm, 5x100 mm and 5x120 mm, each with a TX25 drive. The corresponding setting tool with a suitable bit is also available through fischer.
