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


No over-tightening or stripping and high feed


  • Higher power transmission in hardwoods due to reinforced, asymmetrical thread flank geometry of the coarse 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
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

  • ASSY 4, ASSYplus 4 and ASSYplus 4 FT chipboard screws are optimised for use in wood and wood materials. For applications in plastic anchors where load capacity can also be reduced, use only screws without an optimised thread tip (tip with milling ribs, drill tip, self-clearing groove etc.), such as the ASSY D screws with countersunk head or pan head
