Key Features
  • Full-thread screw made of high-quality austenitic A2 stainless steel.
  • Visually pleasing, rounded raised countersunk head for fastening metal to wood in outdoor areas exposed to the elements.
  • Ideal power transmission thanks to RW drive with larger contact area at the bit.
  • More stability, one-handed working, precise positioning due to tight-fit recess and perfect fit of the bit.
  • Fewer bit changes, one bit for many screw diameters with compatibility to previous AW drive.
  • Form-fit connection of the 90° countersunk head to metal fittings with 90° countersinks or in wooden products with high bulk density.
  • Visually appealing connections due to lens-shaped, rounded head.
  • Pulling together without head milling due to lack of milling elements; head is inserted by pressing.
  • Higher breaking torque and power transmission in hardwoods due to reinforced, asymmetrical thread flank geometry.
  • Better anchoring thanks to higher thread flanks.
  • Smooth thread start ensures optimized recessing and biting of the screw.
  • Reduced splitting effect due to displacement effect of dome-shaped milling elements in the tip.
  • Friction-reduced thread rotation allows reduction of screw-in force.
  • Stainless mounting for accessible wood connections in outdoor areas exposed to weathering.
  • Made of austenitic, non-magnetic, and non-rusting A2 stainless steel.
  • Suitable for use in rural or urban environments.
