RW recess ensures optimal power transmission
- Larger contact surface at the bit offers increased power
- 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 multiple screw diameters
- Compatibility with previous AW recess
Easy countersinking in hardwood/softwood with lots of knots as well as in hard manufactured boards
- Very high milling performance due to milling ribs located in the countersunk head
No over-tightening with high feed
- Higher power transmission in compact and hard woods due to coarse thread with reinforced, asymmetrical thread flank geometry
- Better anchorage due to higher thread flanks
Ideal for friction-free screwing in plastic, such as in anchors or in homogeneous highly compressed engineered wood
- Screw engages rapidly thanks to the continuous thread right up to the tip of the screw
- Non-spreading screwing in thanks to tip geometry without any component to reduce splitting
- Austenitic stainless steel is characterised by a high degree of corrosion resistance against aggressive industrial air, sea air, tap water, river water, mine water and salt water, as well as woods containing tannic acid. It has limited resistance to acid and is not suitable for atmospheres containing chlorine gas
- We recommend using the Würth software or corresponding design aids for planning and designing your installation. Dimensioning of ASSY screws can be carried out in the Würth timber construction software from a screw dia. of 5 mm
- ASSY 4, ASSYplus 4 and ASSYplus 4 VG chipboard screws are optimised for use in wood and engineered wood. For applications in plastic anchors where a reduction in the admissible load may occur, only use 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

For wood-to-wood connections designed to be joined tightly
The partial thread starting immediately below the shank allows for wood-to-wood connections designed to be joined tightly. In this case, the thread is positioned entirely in the lower component.
Can be used for outdoor applications and utilisation class 3
- To increase the joining effect or head penetration resistance, we recommend using the product in conjunction with precisely fitting washers for ASSY 4
- ASSY screws are approved for quasi-static loads
- For optimal use of the screw, use the RW bit that fits exactly
- Partial-thread screws are ideal for connecting timber components. To ensure the components are optimally joined, the components must not be thicker than the length of the screw shank
