Durable & material-saving:
- The system means fewer screws are required. With repeated reuse, the required number of screws also falls for each project/application
Lower dismantling costs:
- Screws can be found again more quickly and the drive easily exposed (concrete sludge can be removed quickly), speeding up removal and reducing working time.
Quicker and more secure installation - even under difficult conditions:
- The long bit guide, magnetic screw holder and precise positioning enable quick biting and prompt insertion of the screw - even in difficult installation situations.
- We recommend using the Würth software or corresponding design aids for planning and designing your installation. Dimensioning of ASSY screws can be carried out in the Würth 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 fixings 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
