Ideal power transmission due to RW recess


  • More power due to a larger contact surface at the bit

  • More stability, one-handed working and 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 recess


Significantly reduces the force required to screw in the screw


  • Minimal splitting when the shank contacts the wood due to material displacement by 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 end mill into the thread

  • Reduced wear and tear on application tools


No over-tightening with high feed performance


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

  • Better anchorage due to higher thread flanks


Smooth thread start ensures optimised piercing and biting of the screw


  • Minimal splitting due to material displacement by the dome-shaped milling elements in the tip

  • Minimal friction when screwing in the thread reduces the amount of force required


High strength values and ductility


  • Tailored heat treatment guarantees high strength values and at the same time ensures high ductility
Notice
  • We recommend using the Würth software or corresponding design aids for planning and designing your installation. Design of ASSY screws can be carried out in the Würth timber construction software from a screw dia. of 5 mm

  • Due to mechanical force exerted by the bit during the screw-in process, corrosion resistance at the screw recess can be adversely affected.

  • Do not use the screw in applications with direct exposure to the weather or in wet 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 the atmosphere contains chlorine, use HCR stainless steel screws

  • ASSY 4, ASSYplus 4 and ASSYplus 4 VG chipboard screws are optimised for use in timber and engineered wood. For applications in plastic anchors where the working load 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
