The special power drive – T-STAR plus – is a so-called internal hexagon. Compared to less precise drive types like Philips or Pozidriv, the contact area of our T-STAR plus increases manifold, and the T-STAR plus bits always fit optimally in the screw head. The resulting best possible, precise power transmission from the driver to the screw through T-STAR plus allows for simple and extremely fast work, and significantly more efficiently than with all other drives.
What this means for you: The annoying slipping of the bit from the screw head is a thing of the past; you can complete entire series of screw connections in no time!
In contrast to partial threads, the full thread on most of our full-thread screws extends over the entire or nearly the entire length from the tip to the head. The more thread turns a screw has, the greater the tensile and compressive forces that can be absorbed by these screws. We particularly take advantage of this in structural timber construction, where full-thread screws are used for high-load timber connections.
What this means for you: You can fully trust in the load-bearing capacity of timber connections with full-thread screws, with no need for unsightly galvanized fittings.
Our designation 4CUT for the tip of our screws describes the fact that they are not round but shaped as a square. These four edges displace the wood fibres during screwing and thus create space for the core diameter of the screw. The otherwise unavoidable spreading pressure exerted by the core in the wood is effectively reduced, and the splitting of the wood near the edge is minimised. The required torque of the cordless screwdriver is also reduced, as the core of the screw does not have to "squeeze" into the wood.
What this means for you: Even in the otherwise tear-prone edge area of your workpiece, almost no pre-drilling is necessary anymore! With the 4CUT, you save an entire working step.
The abbreviation A2 in our stainless steel screws comes from the alloy of the steel. A stands for "Austenite", a mixture of iron, carbon, and the alloying elements chromium, nickel, and molybdenum. The 2 (1-5) indicates the alloy grade, that is, the content of chromium and nickel.
Screws made of stainless steel A2 provide high protection against corrosion and medium strength. Their resistance to seawater and acids, however, is low. Therefore, they are used in outdoor applications far from coastal areas and perform their service reliably for a long time.
What this means for you: With our stainless steel A2 screws, you are well equipped against corrosion for almost all construction projects away from coastal areas.
