Parafuso Fischer 566333 100 mm aço galvanizado 50 unid.

The Fischer PowerFast II (FPF II-WTP BC) is a zinc-plated steel wood construction screw with a flange head, TX star recess drive and partial thread. With a length of 100 mm and an 8 mm thread diameter, this screw is designed for timber connections and offers increased head pull-through resistance and firm clamping of wooden components. The pack contains 50 screws and the product is covered by a European Technical Assessment for added safety.

Advantages

The patented core cutter geometry mills and extracts wood dust precisely, allowing small edge and center distances. A three-ribbed screw tip enables fast biting and pre-milling, reducing splitting and speeding up setting. An increased thread pitch lowers installation time, while a high-performance easy-glide coating and a matched shank-miller reduce screw-in torque for smoother installation and longer battery life. The larger flange head diameter provides higher pull-out resistance compared with countersunk head screws and improves the ability to pull components together.

Suitable for

• Timber frame connections and structural wood joints
• Fixing wooden beams, posts and planks
• General carpentry and wood construction projects
• Applications requiring high head pull-through resistance

How to use

Position the screw so the unthreaded shank section pulls the joined wooden components together while the partial thread secures the outer element. Drive the screw with a matching TX bit and appropriate power setting; the easy-glide coating and shank-miller reduce insertion torque, so pre-drilling is often not necessary for many timber applications. Apply steady pressure and maintain alignment to avoid tilting. Use suitable personal protective equipment and follow the European Technical Assessment and local building codes where applicable.

Recommendations

For best results in structural timber work, use the Fischer PowerFast II screws where higher head pull-through resistance and fast installation are required. Pre-drill only when working near edges or with very dense wood species, and choose appropriate screw length to ensure secure penetration into the receiving timber.
