Skrutka Fischer 566334 120 mm pozinkovaná oceľ 50 ks

Fischer PowerFast II wood construction screw (MPN 566334) is a zinc-plated steel, partially threaded screw with a flange head and TX (Torx) star recess designed for timber connections. It measures 120 mm in length with an 80 mm thread length and an 8 mm nominal diameter. Supplied in packs of 50, this screw is engineered to provide secure clamping of wooden elements and increased resistance against head pull-through when joining components.

Advantages

The patented core cutter geometry mills wood precisely and extracts wood dust efficiently, enabling reduced edge and center distances and flexible wood construction layouts. A three-ribbed tip provides rapid biting and pre-milling for fast setting while reducing splitting. An increased thread pitch shortens installation time. The easy-glide high-performance coating and the redesigned shank-miller together lower screw-in torque, reducing required driving force and battery consumption. The larger flange head achieves higher pull-out resistance compared with countersunk head screws and improves the clamp effect between parts.

Suitable for

• Timber-to-timber connections in structural and non-structural woodwork
• Exterior and interior wood constructions where zinc-plated corrosion protection is acceptable
• Applications requiring strong clamping force and reduced head pull-through

How to use

Select an appropriate TX bit matching the star recess and use a cordless or corded driver with torque control. Position the screw so the unthreaded shank section pulls the joined wooden components tightly together while the threaded portion engages the receiving timber. In most timber applications the PowerFast II can be driven without pre-drilling due to its core-cutter and tip design; however, pre-drilling is recommended for very close edge distances, hard or brittle wood species, or where precise alignment is required. Drive the screw until the flange head sits flush against the surface and the required clamp is achieved.

Recommendations

For longer fastener and battery life, use moderate torque settings and apply steady pressure during installation. Verify that zinc plating is suitable for the environment; choose stainless or hot-dip galvanized variants for higher corrosion resistance if required.
