ASSY®plus 4 P CSMR wooden plate screw Hardened zinc-plated steel partial thread with underhead thread countersunk head

Partial thread screw with underhead thread countersunk milling head and high joining effect. Suitable for gap-free fastening, close to edges without pre-drilling of wooden composite boards or solid woods. The firm hold of the underhead thread enables connections without an assembly gap even with lightweight wooden fibre boards and the screw head ending at the board surface.

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 bits)

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

  • Quick screwing due to gentle start of thread


Easy countersinking in hardwood/softwood with high knot content as well as hard wood fibreboards


  • Very high milling performance due to milling ribs located at the countersunk head


Maximum reliability of the screw connection due to asymmetrical single thread


  • Optimal matching of drill tip and thread geometry

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


High strength values and ductility


  • Adjusted heat treatment guarantees high strength values and high ductility
Notice
  • Do not use the screw in applications with direct exposure to the elements or in humid rooms with atmospheres containing chlorine gas. Please use ASSYplus 4 stainless steel screws for outdoor applications and rooms with constant high humidity

  • 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

  • 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
