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


Clean countersinking in softwood or wood material


  • Easy countersinking of screw head in wood thanks to optimised milling pockets

  • No chipping in coated chipboards due to improved milling effect and increased number of milling pockets up to ∅ 4.5 mm

  • Perfect fit of 90° head in fitting parts with metal countersinks


Visually appealing countersunk finish in wood-wood applications or precise countersunk finish in metal-wood applications thanks to innovative milled pockets


  • Optimum balance between pulling together and countersinking

  • Perfect countersinking in coated chipboard

  • Clean finish of the countersunk head in solid wood

  • Braking effect on metal and milling effect on wood

  • Optimised number of milled pockets depending on the application


Highest power transmission in the tensile and compressive direction


  • Symmetrical high-performance thread matched to the pre-drilling performance of the drill bit tip

  • For high-load wood/wood connections regardless of the load direction


Compact screw connections and small material cross-sections due to effective drill bit tip


  • Extremely short permitted edge distances e.g. 3xd, making ASSY screws ∅ 8 mm usable for beam widths 60 mm

  • No pre-drilling required

  • The wood does not split and rupture

  • Little run-off of long screws


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. Use the Würth timber construction software for dimensioning of ASSY screws from a diameter of 5 mm

  • Do not use for screw applications with direct exposure to the elements or in humid rooms with atmospheres containing chlorine gas

  • 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
