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, one 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 fastening due to gentle start of thread
Clean countersinking in softwood/hardwood with high knot content
- Small, lens-shaped 60° countersunk head for visually appealing connections
- Very high milling performance due to milling ribs located at the countersunk head
Maximum reliability of the screw connection due to asymmetrical single thread
- Optimum 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
- 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 dimensioning your assembly. ASSY screws can be dimensioned 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
ETA-11/0190 approved
The requirements of the European Technical Approval (ETA) must be observed.
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 second component once screwed in.
- For optimum use of the screw, use the RW bit that fits exactly
- Partial threaded screws are ideal for connecting wooden components. To achieve optimum component assembly, the component thickness to be joined tightly must not be greater than the shank length
- ASSY screws are approved for quasi-static loads
