Ideal power transmission due to the RW recess
- More power due 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 recess
Precise positioning and very clean drilling due to advanced centring drill tip
- Chip-free positioning and drilling
- Powerful and precise drilling due to drilling cutting edges (similar to Forstner bit)
- Precise positioning on hard surfaces without slipping due to centring pin
- Quick screwing due to gentle thread start
Easy countersinking in hardwoods and softwoods
- Visually appealing connections due to lens-shaped, rounded head
- High milling performance and chip collection for clean countersinking of the head in softwood/hardwood
- For universal use in wood and metal connections due to milling pockets integrated in the countersunk head
- Can be combined with 90° metal countersinks
Maximum reliability of the screw connection due to asymmetrical single-start thread
- Optimal combination of drill tip and thread geometry
- Excellent anchorage in wood due to asymmetrical arrangement of thread flanks
Stainless for use in 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 anti-friction coating for easy screwing
- We recommend using the Würth software or corresponding design aids for planning and dimensioning 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 woods. For applications in plastic anchors where the load 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
Proof of performance ETA-11/0190
The requirements of the European Technical Approval (ETA) must be observed.
Datasheets(X)
For a fixed connection between two wooden elements
The slightly inclined grooves incorporated into the shank area enable the fixed connection of two wooden elements, even when already installed. Any creaking caused by the drying and swelling of the wooden components is reduced. The mechanical fracture properties of the screw are also increased.
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 connecting wooden components. For optimal joining together of the components, the components to be fixed must not be thicker than the length of the shank
- ASSY screws are approved for quasi-static loads
- ASSY stainless steel screws can be used to install hardwood decking and flooring. Pre-drilling is recommended for tropical woods with high bulk density
