Ruuvi Fischer 568167 220 mm sinkkipinnoitettu teräs 50 kpl

The Fischer PowerFast II FPF II-WTP BC is a powerful wood construction screw with a flange head, TX star recess drive and partial thread. Made of zinc‑plated steel and measuring 220 mm in length with an 8 mm diameter and a 100 mm thread length, this screw is intended for timber constructions where firm clamping and high pull-through resistance are required. The flange head increases the bearing area and reduces the risk of the head pulling through the joined parts. The partially threaded design allows the screw to draw wooden elements tightly together while the thread profile and tip design enable fast engagement and reliable setting.

Advantages

The patented core cutter geometry mills and extracts wood dust precisely, allowing smaller edge and center distances and enabling a variety of wood constructions. A three‑ribbed tip ensures rapid biting and pre‑milling to reduce splitting. Increased thread pitch shortens installation time and improves work economy. An easy‑glide coating lowers screw‑in torque to prolong battery life and smooth installation. The matched shank‑miller further reduces driving resistance. Compared with countersunk screws, the larger flange head produces higher pull‑out resistance and improves performance when pulling components together.

Suitable for

• Timber frame connections
• Attaching beams and joists
• Deck and outdoor wooden structures (where zinc plating is appropriate)
• General wood construction and structural timber joints

How to use

Select an appropriate drill or bit for installation if pre‑drilling is required by the timber type and local practice; the screw is designed for easy insertion and often can be driven without pre‑drilling thanks to its core‑miller and sharp tip. Use a TX/Torx driver that matches the star recess to avoid cam‑out. Position the partially threaded screw so the smooth shank portion spans the surfaces to be pulled together and drive until the flange head is firmly bearing on the outer element. Apply steady pressure and controlled speed to reduce splitting and avoid over‑torquing.

Recommendations

For structural timber applications verify compatibility with local building codes and, where necessary, use corrosion‑resistant fasteners suited to the environment. For optimal results in hardwoods or near edges, consider pilot holes according to timber density; always use the correct TX bit and a drill or driver with sufficient torque.
