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


Significant reduction in the amount of force required when fastening in the screw


  • Less splitting when immersing the shank due to the displacement milling effect of the milling shank

  • Minimised risk of screw breakage due to high breaking torque

  • Reduced risk of injury from protruding metal chips due to the integration of the milling shank into the thread

  • High protection of the application tools


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


  • Low gap 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


High strength values and ductility


  • Adjusted heat treatment guarantees high strength values and high ductility
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 (coupling cutter tip, drill bit tip, self-clearing groove etc.), such as the ASSY D screws with countersunk head or pan head
