Wood screws with wax coating: The unique wax coating significantly reduces the required screw-in torque. This makes assembly faster and easier and also extends the operating time of battery-powered tools.
Torx screw set with double thread: Additional spirals at the tip make it easier to screw in, which allows the wood to be grasped faster and less pressure is required.
The screw head with TX drive ensures secure and proper attachment. Thanks to the special TX drive, optimal transmission of the torque is ensured. Discover an extensive range of Torx screws, including wood screws (3 x 400 mm) and chipboard screws. Torx screw assortment.
Milling tip / cutting notches: The special shape of the cutter tip reduces resistance when screwing in by 20%, which extends the life of batteries and tools. The cutting notches on the thread cut the wood fibres of the grain when screwing in. Suitable for solid wood, glued solid wood, wood-based boards, plywood, OSB panels and other wood materials.
Drill bit: Our adjusting screws are equipped with a boring cutter that makes it easier to insert the screw by expanding the hole in the component and reducing the required torque. Perfect as construction screws, especially for wood construction and joist hangers.
