Key Features
  • Full threaded screw with raised countersunk head and restraining ribs for gap-free fastening close to edges.
  • Mounting of metal fittings to timber windows without pre-drilling the wood.
  • 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.
  • Visually appealing connections in window construction.
  • Lens-shaped, rounded head for a visually appealing window fitting connection.
  • Spring-loaded effect of the restraining ribs prevents the screw from overturning and destroying the head.
  • Maximum reliability of the screw connection due to asymmetrical single thread.
  • Optimal matching of drill tip and thread geometry.
  • Excellent anchoring in wood due to asymmetrical arrangement of thread flanks.
  • Small edge distances possible due to wedge-shaped drill tip with parallel cutting edges.
