The fischer terrace screw FPS-ST with flat countersunk head, TX star recess drive and partial locking thread is ideal for the surface-flush, splinter-free screwing together of terrace subframe systems and wooden decking. The TX star recess drive enables top force transmission with maximum bit stability. The innovative special thread shape facilitates the screwing process, even in hard woods. In addition, the partial thread enables the firm screwing of the decking to the subframe system. The additional locking thread ensures the lasting fixing of the panels and prevents individual boards from coming loose. The stainless steel terrace screw is highly resistant to weather and tannic acid.
