Fischer 7.5 x 62 FFSZ Window Frame Fixing Screws (100 Box) 532907

The fischer window frame screw FFSZ (with a length of up to 302 mm) with a cylinder head is a special screw for the cost-effective installation of wooden window frames without plugs. 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.
