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
Form-fitting connection to metal fittings or in wooden products with high bulk density
- For fitting connection with full-thread steel screws
- Perfect fit of 90° head in fitting parts with metal countersinks
- Pulls together without head milling due to lack of milling elements below the head
- The head is inserted by pressing
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 reduction of the screw-in force to be applied
- We recommend using the Würth software or the corresponding design aids for planning and dimensioning your assembly. Dimensions of the ASSY screws can be carried out in the Würth timber construction software from a ∅ 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 atmosphere is chlorine-containing, HCR stainless steel screws
- 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 (coupling cutter tip, drill bit 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
Datasheets(X)
For wood to wood connections designed to pull together
The partial thread starting immediately below the shank allows for wood to wood connections designed to pull together. The screw thread is positioned entirely in the lower component once screwed in.
For applications in utilisation class 1
- High-quality surface protection, burnished, chromium(VI)-free
- Suitable for use in utilisation class 1 (indoors) according to EN 1995-1-1:2010-12 + DIN SPEC 1052-100:2013-08
- ASSY screws are approved for quasi-static loads
- For optimum use of the screw, the right-size RW bit must be used
- Full-thread screws are suitable for secure fastening of fittings or thin materials. The screw length to be selected should be less than the plate thickness of the screw surface
