Screw Fischer 566332 80 mm Zinc Plated Steel 50 pcs

The Fischer PowerFast II FPF II-WTP BC is a wood construction screw with a flange head, TX (Torx) star drive and partial thread, designed for timber and general woodworking applications. Made of zinc-plated steel, this 80 mm screw with an 8 mm thread diameter provides secure clamping of wooden components and increased resistance to head pull-through. Each pack contains 50 screws; the product has European Technical Assessment for added safety.

Advantages

The patented core-cutter geometry enables precise milling and effective removal of wood dust, allowing small edge and center distances for varied wood constructions. A screw tip with three ribs delivers rapid bite and pre-milling, reducing splitting and enabling fast setting. Increased thread pitch shortens installation time while the easy-glide coating lowers screw-in torque for smoother installation and longer battery life. A redesigned shank-miller works with the core-miller to further reduce driving resistance. The larger flange head diameter yields higher pull-out resistance compared with countersunk head screws, improving clamping when joining components.

Suitable for

• Timber framing and structural wood connections
• Decking, joist and beam assembly
• General carpentry and furniture construction
• Indoor and outdoor woodworking projects where corrosion protection is required (zinc-plated)

How to use

Use an appropriate TX bit in a compatible drill or impact driver. Position the screw so the partially threaded shaft spans the joint to be clamped, allowing the unthreaded shank to pull the components together as the head is tightened. In most wood types the PowerFast II can be driven without pre-drilling thanks to its thread and tip design; however, pre-drilling is recommended for very hard or brittle woods and for edge-close placements. Apply steady pressure and drive at a controlled speed until the flange head sits flush against the surface.

Recommendations

For optimal performance, use a correct-size Torx bit, maintain battery charge for cordless drivers to ensure consistent torque, and consider pre-drilling in hardwoods or where minimal splitting risk is required. Store screws in a dry place to preserve the zinc plating.
