622 pieces in system case 4.4.1. ASSY® 4 chipboard screws countersunk milling head, partial thread, RW, zinc-plated steel, blue passivated (A2K)

Ideal power transmission thanks to RW recess


  • More power due to larger contact area 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 drive


Significant reduction in the amount of force required when screwing in the screw


  • Minimal splitting when shank contacts wood due to material displacement of the milling shank

  • Minimised risk of screw breakage due to high breaking torque

  • Reduced risk of injury from protruding metal chips due to the milling shank integrated in the thread

  • Reduced wear and tear on application tools


No over-tightening with high feed performance


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

  • Better anchorage thanks to higher thread flanks


Smooth thread start ensures optimised recessing and biting of the screw


  • Minimal splitting due to material displacement of 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


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

  • Do not use the screw in applications with direct exposure to the elements or in humid 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, HCR stainless steel screws

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

ETA-11/0190 approved

The requirements of the European Technical Approval (ETA) must be observed

Application area

For wood-to-wood connections designed to join tightly


The partial thread starting immediately below the shank allows for wood-to-wood connections designed to join tightly. In this case the thread is positioned entirely in the lower second component.



For applications in utilisation class 1 and 2 (from dia. > 4 mm)


  • High-quality surface protection, zinc, blue passivated, chromium(VI)-free, up to dia. 4 mm A2K 5 µm, from dia. 4.5 mm A3K 8 µm layer thickness

  • Suitable for use in utilisation class 1 (indoor areas) and from dia. > 4 mm in utilisation class 2 (wet areas or covered outdoor areas) in accordance with EN 1995-1-1:2010-12 + DIN SPEC 1052-100:2013-08

  • For screws from dia. 4.5 mm with a zinc layer thickness of 8 µm and Cr(III) passivation, the requirement of classification T2/C2 is fulfilled in accordance with prEN 14592:2017 (D)
Instructions
  • ASSY screws are approved for quasi-static loads

  • For optimum use of the screw, use the RW bit that fits exactly

  • Full-thread screws are suitable for secure fastening of metal fittings or thin materials. Select a screw length that is less than the plate thickness of the screw surface
