- The fischer window frame screw FFS is a special screw (with a length of up to 302 mm) with a flat head for the cost-effective installation of window frames without plugs
- The flat head design is particularly suitable for window frames made from aluminium and plastic
- The ift Rosenheim Testing Institute confirms their special suitability for the fixing of plastic widows into brick masonry
- The small drill hole diameter of 6 mm and the screwing-in of the screw without cleaning the drill hole enable efficient series fixings
- The high-deep thread on the screw tip and the milled ribbing reduce the screw-in torque and enable an energy-saving installation
- The continuous special thread prevents the window frame from being pulled against the substrate
- This means that the frame is secured to the building material without tensile force or stress
Top Features
- Cost-effective screw installation without plugs
- For all solid and perforated building materials
- Fast series installation due to small drill hole diameter of 6 mm
- Stress-free, durable fixing of the frame
- Continuous thread prevents the frame from being pulled
- Power-saving installation: Special thread reduces force required for screwing
Advantages
- Screw installation without plug for economical processing
- The small drill bit diameter of 6 mm allows for efficient series installation
- The continuous thread ensures a stress-free fixing of the frame in the substrate
- The high-low-thread at the screw tip as well as several cutting notches reduce the amount of force required for screwing in the screws
- The installation process can be completed without excessive effort
- According to the ift Rosenheim suitable for the fixation of a plastic window in brick masonry
