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, 1 bit for many screw diameters
- Compatibility with previous AW drive
Precise positioning and very clean tapping due to advanced centring drill tip
- Positioning and tapping without chipping
- Maximum drilling performance and precise drilling process through drilling cutting edges (similar to a Forstner bit)
- Precise positioning on hard surfaces without slipping thanks to centring pin
- Quick screwing due to smooth thread start
Unobtrusive mounting of wooden components
- Small head diameter for unobtrusive mounting
- Low splitting effect when countersinking the screw head
Maximum screw connection safety due to the asymmetrical single thread
- Optimal matching of drill tip and thread geometry
- Excellent anchoring in wood due to asymmetrical arrangement of thread flanks
Stainless mounting for accessible wood connections in outdoor areas exposed to weathering
- Made of austenitic, non-magnetic and non-rusting A2 stainless steel in antique design
- Can be used in rural or urban environments or industrial atmospheres without significant exposure to chlorides or SO2
- With friction-reducing slide coating for easy screwing
- We recommend using the Würth software or the corresponding design aids for planning and designing your assembly. ASSY screws can be designed from a ∅ 5 mm in the Würth timber construction software
- ASSY 4, ASSYplus 4, and ASSYplus 4 FT chipboard screws are optimised for use in wood and engineered woods. For applications in plastic anchors where load capacity can also be reduced, only use screws without an optimised threaded tip (tip with milling ribs, drill bit tip, self-clearing groove, etc.), such as the ASSY D screws with countersunk head or pan head

For the fixed connection of two wooden elements
The underhead thread beneath the head with even thread pitch and equal external diameter enables two wooden elements to be permanently connected in the assembled state. Any creaking caused by the drying and swelling of the wooden components is excluded. Integrated shaft grooves improve pulling together.
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 optimum use of the screw, use the exact fitting RW bit.
- Partial-thread screws are ideal for connecting wood-wood structures. In order to achieve the best possible component assembly, the thickness of the component to be mounted must not be greater than the length of the shank
- ASSY screws are approved for quasi-static loads
- ASSY stainless steel screws can be used to attach hardwood decking and flooring. Pre-drilling is recommended for tropical timber with high bulk density
