TX drive


  • No wobbling, optimal centring and longer service life


Washer head

  • Improved tightening of joints, even in deformed wood


Coarse thread


  • Faster screwing than with single-start thread, delivers time savings of up to 20 %


Surface


  • Zinc-plated, blue passivated

  • Increased layer thickness from dia. 4.5 mm, min. 8 µm (A3K)

  • Chromium(VI)-free


Patented threaded tip included


  • Faster screwing

  • Minimised splitting

  • Lower torque when screwing in

  • No pre-drilling required


Friction part
