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


Precise positioning and very clean drilling due to advanced centring drill tip


  • Positioning and drilling without chipping

  • Maximum drilling performance and precise drilling process through drilling cutting edges (similar to Forstner bit)

  • Precise positioning on hard surfaces without slipping thanks to centring pin

  • Quick screwing due to gentle start of thread


Well-designed, unobtrusive mounting of wooden components


  • Small screw head with lens-shaped rounded head for well-designed, unobtrusive mounting

  • Highly effective milling ribs prevent narrow wooden profiles from splitting


Maximum reliability of the screw connection due to asymmetrical single thread


  • Optimum matching of drill bit tip and thread geometry

  • Excellent anchoring in wood due to asymmetrical arrangement of thread flanks


Stainless mounting for accessible wood connections in outdoor areas exposed to weathering


  • Made of austenitic, non-magnetic and non-rusting A4 stainless steel

  • Can be used in rural or urban environments or industrial atmospheres without significant exposure to chlorides or SO2

  • With friction-reducing slide coating for easy screwing
Notice
  • We recommend using the Würth software or the corresponding design aids for planning and dimensioning your assembly. ASSY screws can be dimensioned 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 bit tip, self-clearing groove etc.), such as the ASSY D screws with countersunk head or pan head
