Universal partial-thread screw for fast, gap-free fastening of wood-wood connections in furniture construction, interior fitting or wood construction in indoor dry or sheltered areas
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, 1 bit for many screw diameters
- Compatibility with previous AW drive
Significant reduction in the amount of force required when screwing in the screw
- Low gap effect when immersing the shank due to the displacement milling effect 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 integration of the milling shank into the thread
- High protection of the application tools
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 anchorage 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
High strength values and ductility
- Adjusted heat treatment guarantees high strength values and high ductility
Proof of Performance
ETA-11/0190 approved
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
- 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 contains chlorine, 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 (tip with milling ribs, drill tip, self-clearing groove etc.), such as the ASSY D screws with countersunk head or pan head
Application area
ETA-11/0190 approved
The requirements of the European Technical Approval (ETA) must be observed
Product information
Datasheets(X)
Application area
Parallel drive size RW30 is available for window applications with a diameter of 6 mm. This makes it easier to combine with AMO screws equipped with RW30.
For wood-to-wood connections designed for contraction
The partial thread starting immediately below the shank allows for wood-to-wood connections designed for contraction. In this case the thread is positioned entirely in the lower second component.
For applications in utilisation classes 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 zinc layer thickness 8 µm with Cr(III) passivation, the requirement of classification T2/C2 is fulfilled in accordance with prEN 14592:2017 (D)
Instructions
- To increase the joining effect or head pull-through resistance, combining with perfectly fitting washers for ASSY 4 is recommended
- ASSY screws are approved for quasi-static loads
- For optimum use of the screw, the right-size RW bit must be used
- Partial-thread screws are ideal for connecting wooden components. To achieve optimum assembly of the components, the components to be fixed must not be thicker than the length of the shank
