Eco-Duo Inox

Available from May 2026

The Eco-Duo Inox screw made of stainless steel is a wood construction screw that is mainly used in outdoor settings. Thanks to the special thread below its head, the screw optimally tightens the components to be connected, so that there is no gap. The screw has an ornamental head with TX drive.

Advantages

• Ornamental head with milling ribs
• Underhead thread – ensures optimal tightening
• No need to use the impact setting during screwing in thanks to the TX drive
• Thread – saw teeth in the thread ensure that wood fibres are cut through quickly, which makes the screwing in easier
