The fischer wood construction screw Power-Fast FPF-WT YZP is a powerful wood construction screw with a flat head, TX star recess drive and partial thread for use in timber constructions. The flat head with TX star recess guarantees the greater pulling together of the parts being joined and significantly increased resistance against the head being pulled through the components. The partial thread also enables the firm attachment of wooden elements to each other. The European Technical Approval guarantees added safety. The Power-Fast is particularly easy to screw in without pre-drilling thanks to the thread shape. The Power-Fast 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.
