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, 1 bit for many screw diameters

  • Compatibility with previous AW drive


Visually appealing fasteners in window construction


  • Lens-shaped, rounded head for a visually appealing window fitting connection

  • The spring-loaded effect of the restraining ribs prevents the screw from overturning and destroying the head


Less tendency of the wood to split and very few blow-outs


  • Blow-outs are avoided to a high degree thanks to the punching effect

  • Minimal splitting forces, especially when screwing in at edges

  • Reduction of the screw-in torque
Notice
  • 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

  • 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 is chlorine-containing, 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
