Ideal power transmission thanks to RW recess
- More power thanks to a larger contact surface at the bit
- 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 many screw diameters
- Compatibility with previous AW drive
Precise positioning and very clean drilling due to advanced centring drill tip
- Chip-free positioning and drilling
- Powerful and precise drilling thanks to drilling cutting edges (similar to Forstner bit)
- Precise positioning on hard surfaces without slipping thanks to centring pin
- Quick screwing thanks to gentle thread start
Well-designed, unobtrusive mounting of narrow wooden components
- Small screw head painted white with lens-shaped rounded head for stylish, unobtrusive mounting
- Highly effective milling ribs prevent narrow wooden profiles from splitting
Maximum reliability of the screw connection due to asymmetrical single thread
- Optimal matching of drill tip and thread geometry
- Excellent anchorage in wood due to asymmetrical arrangement of thread flanks
High strength values and ductility
- A coordinated heat treatment guarantees high strength values and at the same time ensures high ductility
- Do not use the screw in applications with direct exposure to the elements or in humid rooms with atmospheres containing chlorine gas. Please use ASSYplus 4 stainless steel screws for outdoor applications and rooms with constant high humidity
- 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
- 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
For wood-wood connections designed to pull together
The partial thread starting immediately below the shank allows for wood-wood connections designed to pull together. The screw thread is positioned entirely in the lower component once screwed in.
Unobtrusive mounting
Colour adaptation to the component by painting the screw head.
- 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
