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
Precise positioning and very clean drilling due to advanced centring drill tip
- Positioning and drilling without chipping
- Maximum drilling performance and precise drilling process through drilling cutting edges (similar to Forstner bit)
- Precise positioning on hard surfaces without slipping thanks to centring pin
- Quick screwing thanks to smooth thread start
Clean countersinking in softwood/hardwood with many knots
- Small, lens-shaped 60° countersunk head for visually appealing connections
- Very high milling performance due to milling edges located in the countersunk head
Maximum reliability of the screw connection due to asymmetrical single thread
- Optimal matching of drill tip and thread geometry
- Excellent anchoring in wood due to asymmetrical arrangement of thread flanks
Stainless fastening for accessible wood connections in outdoor areas exposed to weathering
- Made of austenitic, non-magnetic and non-rusting A2 stainless steel
- Can be used in a rural or urban environment or in an industrial atmosphere without significant exposure to chlorides or SO2
- With friction-reducing coating for easy screwing
- We recommend using the Wurth software or the corresponding design aids for planning and designing your project. Dimensioning the ASSY screws can be carried out in the Wurth timber construction software from a diameter of 5 mm
- ASSY 4, ASSYplus 4 and ASSYplus 4 VG chipboard screws are optimised for use in wood and engineered woods. 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
ETA-11/0190 approved
The requirements of the European Technical Approval (ETA) must be observed.
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.
- For optimum use of the screw, use the RW bit that fits exactly
- Partial-thread screws are ideal for wood-to-wood constructions. To achieve optimum component assembly, the component thickness to be fixed must not be greater than the shank length
- ASSY screws are approved for quasi-static loads
