Fischer Window frame screw FFSZ 7.5x112

The Fischer window frame screw FFSZ with a cylindrical head is a special screw designed for the economical assembly of wooden window frames. The screw can be directly screwed into solid and hollow building materials after drilling. The continuous special thread prevents the window frame from being pulled against the substrate, ensuring it is fixed without tension and is durable.

Advantages:

• Screw assembly without dowels for economical processing.
• The small drill hole diameter of 6 mm allows for efficient series assembly.
• The continuous thread enables a pull- and tension-free attachment of the frame to the substrate.
• The high-low thread at the screw tip, along with additional milling ribs, reduces the screwing torque and allows for a gentle assembly.
• Usable with two head shapes for all common frame materials.
• Suitable for fixing plastic windows in brick masonry according to ift Rosenheim.

Applications:

• Window frames made of wood, plastic, and aluminum
• Door frames
• Beams
• Building materials: concrete, hollow bricks, lightweight concrete hollow blocks, lime-sand hollow stones, lime-sand solid stones, lightweight concrete solid stones, solid bricks, aerated concrete

Functionality:
Observe drilling and screwing depths for various building materials according to the table. For recessed mounting in wooden profiles, the cylindrical head screw is recommended. For the assembly of plastic and aluminum profiles, the flat head screw is recommended.
