The Fischer PowerFast FPF II CZP is designed for professional carpenters, furniture makers, and DIY enthusiasts who require high-performance, reliable fastening in timber. These 4mm x 70mm screws provide exceptional pull-through resistance and rapid installation thanks to their specialized geometry, making them ideal for heavy-duty wood connections. A key caveat is that while they are highly efficient in wood, they are specifically optimized for use with PZ2 drivers, requiring the correct tool size to prevent stripping the head.

They feature blue passivated zinc plating for internal and protected use. They are not recommended for permanent outdoor exposure.
In most cases, the three-ribbed tip allows for immediate engagement without pre-drilling. Pre-drilling is only recommended for very dense hardwoods.
The PowerFast II features advanced thread pitch, a specialized wax coating, and unique shank-miller geometry for faster, lower-torque installation.
Yes, they are designed to be used in combination with Fischer expansion plugs like the DuoPower or UX series for masonry fixing.
These screws use a standard PZ2 (Pozidriv size 2) driver bit.
Ensure you are using a correct, high-quality PZ2 bit and that the bit is fully seated before applying pressure.
While designed to reduce splitting, pre-drill a small pilot hole if working within 2cm of a board end or edge.
Check battery charge on your drill and consider a small pilot hole to reduce the load on the screw shank.
To ensure the best results, use a high-quality electric or battery-powered drill equipped with a PZ2 bit. Because these screws are 70mm in length, ensure your pilot hole—if required by the specific wood density—does not exceed the core diameter of the screw to maintain maximum pull-out resistance. While these screws are blue passivated to resist corrosion, avoid using them in direct contact with moisture or chemically treated woods that may accelerate oxidation. Store the remaining screws in a dry, cool environment to preserve the efficacy of the factory-applied wax coating.
