Product description
The screw fixing with lenticular flange head for the stress-free installation of window and door frames.
The fischer metal frame fixing F-M is a special plug for the stress-free, lasting stand-off installation of window and door frames and of squared timbers. It consists of a metal sleeve and a zinc-plated steel screw. The F-M is set in a time-saving push-through installation. When the screw is tightened, the cone is pulled into the plug sleeve and expands against the wall of the drill hole. This ensures a fixation that is free from tensile force and pressure, thus guaranteeing a secure hold in solid and hollow building materials. The F-M is tested for fire resistance class R120, and offers safety for fire-protection-relevant applications.
- The F-M metal frame plug achieves fire resistance R 120. This allows for use in areas where fire resistance is relevant
- The operating principle prevents the window frame from being pulled against the substrate, and ensures a stress-free and long-lasting fixing of the frame
- The special plug geometry anchors the metal and plastic profiles against compressive and tensile loads, and allows for a secure hold of the window frame
- The cover caps (available separately) can be used to discreetly cover the screw heads
Suitable for
- The F-M is suitable for push-through installation
- By tightening the screw, the cone is drawn into the sleeve and the fixing is expanded which wedges it inside the drill hole. The window frames are thus fixed in a stress-free manner
- The maximum installation torque is 5 Nm
