Window frame screws FFS TX30 Head

The economical special screw for window installation

The fischer window frame screw FFS with flat head is a special screw for cost-effective assembly of window frames. After drilling, the screw can be directly driven into solid and perforated building materials. The continuous special thread prevents window frames from being pulled against the substrate. This is then fixed in a stress-free, durable manner.

  • The continuous thread ensures a stress-free fixing of the frame in the substrate.
