The fischer FFS flat-head window frame screw is a specialized screw for economical installation of window frames without dowels. After drilling, the screw can be directly screwed into solid and perforated building materials. The high-low thread at the screw tip and additional milling ribs reduce torque and enable force-saving assembly. The continuous special thread prevents the window frame from being pulled against the floor. This means the frame is secured without tension and ensures long-term durability. The fischer FFS flat-head window frame screw is ideal, for example, for securing wooden, plastic or aluminum window frames, door frames, or square timber into brick masonry.
