Vis de charpente PowerFast II STP

The fischer wood construction screw PowerFast FPF II-STP BC is a powerful wood construction screw with a step countersunk head, TX star recess drive and partial thread for use in timber constructions. The step countersunk head with TX star recess guarantees stronger contraction of the joined parts and significantly increased resistance against the head being pulled through the components. Additionally it´s assessed to countersink the head flush with the surface. The partial thread also enables the firm attachment of wooden elements to each other. The European Technical Assessment guarantees added safety. The PowerFast II is particularly easy to screw in without pre-drilling thanks to the thread shape. The PowerFast II thread reaches into the screw tip and ensures a fast bite. The shank ribs reduce the screwing resistance, thus decreasing the required force and battery power for the installation.
