Screw Fischer 566337 180 mm Zinc plated steel 50 pcs

Fischer PowerFast II FPF II-WTP is a powerful wood construction screw with a flange head, TX star recess drive and partial thread. Made from zinc-plated steel, this 180 mm screw with an 8 mm diameter and a 100 mm thread length is supplied in a pack of 50 and is designed for reliable connections in timber construction. The flange head increases the effective clamping area and improves resistance to head pull-through, while the thread and tip geometry enable fast engagement and secure clamping of wooden components.

Advantages

The patented core cutter geometry mills and evacuates wood dust precisely, allowing smaller edge and center distances and enabling diverse wood constructions. A three-ribbed screw tip ensures quick biting and pre-milling, reducing splitting and enabling fast setting. The increased thread pitch reduces installation time for more economical project completion. A high-performance easy-glide coating and a newly designed shank-miller lower screw-in torque, reducing required force and battery consumption. Compared with countersunk head screws, the larger flange head diameter provides higher pull-out resistance and better performance when pulling components together.

Suitable for

• Timber framing and load-bearing wood constructions
• Wood-to-wood connections where strong clamping is required
• Decking, pergolas, and outdoor wooden structures (with appropriate corrosion protection)
• General carpentry and structural woodwork

How to use

Use a TX driver bit that matches the screw recess and a compatible cordless or corded driver. Position the screw so the partially threaded section pulls the two wooden components tightly together; start driving at low speed to allow the three-ribbed tip to pre-mill and bite. Apply steady pressure and increase speed as the screw engages. For best results, maintain perpendicular alignment to the workpiece and avoid excessive force once the flange head seats to prevent overdriving.

Usage recommendations

For outdoor or corrosive environments, verify that zinc plating meets the required corrosion resistance for your application or choose an alternative with enhanced coating. Pre-drilling is generally not required due to the thread and tip design, but consider pilot holes near edges or in hardwoods to further reduce splitting.
