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


Screw fitting without gaps or bulging in MDF front surfaces


  • Optimisation and extension of the drill tip for screw fittings without gaps or bulging


Powerful connection of e.g. thin fibreboards for furniture back panels


  • Large flat-shaped washer head for a strong connection of e.g. thin fibreboards as furniture back panels

  • Visually appealing flat screw connection

  • Large head diameter with small thread diameter for a strong connection


Maximum pull-out strength and minimum splitting effect


  • Thread attuned to MDF material

  • Optimum distribution of drilling chips through serrated screw core

  • Prevents pressing in the MDF material due to thin core diameter and extra high thread flanks
Notice
  • Do not use the screw in applications with direct exposure to the elements or in humid rooms with atmospheres containing chlorine gas. Please use ASSYplus 4 stainless steel screws for outdoor applications and rooms with constant high humidity

  • We recommend using the Würth software or the corresponding design aids for planning and dimensioning your assembly. Dimensions of the ASSY screws can be carried out in the Würth timber construction software from a ∅ of 5 mm

  • 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
