PowerFast FPF II STP BC

The fischer PowerFast FPF II STP BC is an electro-galvanized, blue passivated screw with partial thread and internal star recess socket. The step countersunk head can also be easily countersunk like the normal countersunk head and has the additional advantage of higher pull-out values due to the large head diameter. The partially threaded version enables wooden elements to be pulled tightly together.
