Key Features
  • Universal partially threaded screw made of high-quality austenitic A2 stainless steel for wood-wood connections (spruce) in outdoor areas exposed to the elements
  • Ideal power transmission thanks to RW drive
  • More power due to larger contact area at the bit
  • More stability, one-handed working, precise positioning due to the tight-fit recess and perfect fit of the bit
  • Fewer bit changes, one bit for many screw diameters
  • Compatibility with previous AW drive
  • Higher breaking torque
  • Higher power transmission in hardwoods due to reinforced, asymmetrical thread flank geometry of the single thread
  • Better anchoring thanks to higher thread flanks
  • Smooth thread start ensures optimised recessing and biting of the screw
  • Reduced splitting effect due to displacement effect of the dome-shaped milling elements in the tip
  • Friction-reduced thread rotation allows reduction of the screw-in force to be applied
  • Stainless mounting for accessible wood connections in outdoor areas exposed to weathering
  • Made of austenitic, non-magnetic and non-rusting A2 stainless steel
  • Can be used in rural or urban environments or industrial atmospheres without significant exposure to chlorides or SO2
  • With friction-reducing slide coating for easy fastening
