Ideal power transmission thanks to RW recess


  • 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


Well-designed, flat and visible metal connection


  • Precise fit and high power transmission when used in pre-drilled round holes in metal thanks to flattened, semi-circular large truss head with flat contact surface under the head and integrated shank reinforcement


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 for a lower screw-in force


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

  • 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
