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


Form-fitting connection to metal fittings or in wooden products with high bulk density


  • For fitting connection with full-thread steel screws

  • Perfect fit of 90° head in fitting parts with metal countersinks

  • Pulls together without head milling due to lack of milling elements below the head

  • The head is inserted by pressing


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


Ideal for friction-free screw fitting in plastic, such as in anchors or in homogeneous highly compressed wooden materials


  • Screw bites rapidly through the continuous thread design to the tip of the screw

  • Non-spreading screwing in thanks to tip geometry without any component to reduce splitting
Notice
  • We recommend using the Würth software or the corresponding design aids for planning and dimensioning your assembly. Use the Würth timber construction software for dimensioning of ASSY screws from a diameter of 5 mm

  • Do not use the screw in applications with direct exposure to the elements or in humid rooms with atmospheres containing chlorine gas. If used outdoors and in rooms that are constantly exposed to high humidity, please use ASSY 4 A2 or A4 stainless steel screws and, if atmosphere contains chlorine, HCR stainless steel screws
