The screw fixing with countersunk head for the stress-free installation of window and door frames.
The fischer metal frame plug F 10 M is a special fixing for stress-free stand-off installation of window and door frames. This consists of a metal sleeve and a countersunk head screw made of zinc-plated steel. The F 10 M is set in the time-saving pre-positioned installation. When the screw is tightened, the cone is pulled into the fixing sleeve and expands itself against the hole wall. This means that the window frame is fixed in a stress-free manner in solid and hollow building materials. The fischer metal frame plug F 10 M is also suitable for squared timbers as well as fixing window and door frames.
