Especially suitable for timber construction/carpentry and for concrete and formwork construction and for all other wood-on-wood screw connections where poorer-grade wood qualities are used.

Tip


The 25° tip enables precision positioning. Screw with mating thread in tip area, which greatly reduces the splitting forces of the wood, especially in the edge area. The screw-in torque is considerably less than with conventional chipboard screws and extends the service life of the processing machine and the bit insert.



thread


The plastic glide-coated asymmetrical coarse thread means a 30% saving in working time.



End mill


The milling section after the thread reduces the screw-in torque by 20%.



Thin shaft


The thin shaft enables a tension-free connection without gaps.



Countersunk milling head


60° countersunk milling head for easy, clean countersinking in solid construction wood and coated wood panel materials.



AW® drive


  • Better force transfer

  • Optimum centring

  • Long tool life

  • Even distribution of force prevents the surface coating from being damaged
Notice

Do not use the screw in applications with direct exposure to the elements, in humid rooms and in atmospheres containing chlorine gas.



The screws are not suitable for outdoor use and for rooms subject to short-term or continuously high moisture levels! Please use ASSY® 3.0 A2 stainless-steel screws in these cases. The surface coatings of nickel and brass are suitable for decorative purposes only = no corrosion protection!



ASSY 3.0 chipboard screws are optimised for use in wooden materials. Use in plastic dowels may cause a reduction in the load-bearing capacity. Therefore, we recommend only using screws without optimised thread tips (drill tip, mating thread, ring thread, serrated edge, self-clearing groove, etc.) in plastic anchors, e.g. Würth ASSY D, prefix number 0151 (countersunk head) and prefix 0153 (pan head)



When using these screws, the ETA-11/0190 specifications must be observed.

Application area

For wood-wood screw connections where poorer-grade wood qualities are used.

Instructions

Screw-in angle 0° to 90°. For coniferous wood or wood-based materials made from softwood, the screw connection is made without pre-drilling. To reduce the edge distances, a pre-drilled hole can be made according to the core diameter. When screwing into hardwood, pre-drill according to ETA-11/0190.
