ASSY^®4. The best performance of all time.

For you, our developers, engineers and production experts have worked together to make the performance of our high-performance screw even better. The result of this intensive innovation work can now be processed daily.

ASSY^®4. The best performance of all time.

The new ASSY^®4. The innovation screw. Made for your maximum performance.

The customer says

"Time is money in crafts. Right from the first use of the ASSY^{^®} 4, we noticed that the screw grips much better and can therefore be screwed in more quickly. The perfectly fitting bits in the various head sizes are a significant time saver. From use in conventional timber construction to solid wood house construction – it is a real pleasure. The improvements are clearly noticeable and we can speak of a clear increase over the previous screw. My team and I are really impressed!"

The developer says

"Due to the tip of the milling cutter running in the opposite direction to the thread, the splitting effect of the wood is considerably reduced without destroying the wood fibres. As a result, the wood is initially displaced during the screw-in process and can expand again after processing, resulting in an optimum hold in the material. At the same time, the force and friction required for screwing in is reduced."

Innovation power meets production competence

1. NEW BIT

The new bit with plug-in effect holds even better and provides more efficiency: 2 bits fit 80% of all screw applications.

2. NEW DRIVE

The larger contact surface on the new RW drive ensures even better power transmission.

3. NEW MILLING POCKETS

The larger number of milling pockets makes it easier to countersink the screw in hard surfaces.

4. NEW END MILL

The end mill is advanced into the thread to facilitate screwing in.

5. NEW THREAD

The new thread offers improved connection. For use in panels in carcase construction etc.

6. NEW TIP

The gently approaching tip with linearly rising tips reduces the splitting effect.
