The chipboard screw with raised countersunk head, TX star recess socket and full thread.
The fischer chipboard screw PowerFast FPF II RZF A4 is a stainless steel A4 screw with raised countersunk head, TX star recess socket and full thread. The small countersunk head with a slight curvature makes the screw visually attractive and enables a flush installation. The TX star recess drive enables top force transmission with maximum bit stability. The chipboard screw with full thread offers a higher extraction resistance due to the longer thread.
