Ideal power transmission thanks to RW recess


  • More power due to larger contact area at the bit


Maximum overtightening safety with high feed performance


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

  • Better anchorage thanks to higher thread flanks


Strong gap-free assembly of components using a second supporting underhead thread with flat incline



Smooth thread start ensures optimised recessing and biting of the screw


  • Low gap effect due to displacement effect of the dome-shaped milling elements in the tip
Notice
  • We recommend using the Würth software or the corresponding design aids for planning and dimensioning your assembly. Dimensioning 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
