The Kraftangriff Kreuzschlitz Z is an evolution of the simple cross-power drive from Philips Screw Company. The difference is that the four sides of the screwdriver blade do not taper towards the tip. This increases the lateral grip for the bit and reduces the cam-out effect, which occurs in conventional cross-power drives due to the tapering, as the torque from the cordless screwdriver pushes the screwdriver bit upwards.

Where the countersunk screw is flat for flush sinking of the screws, the lens countersunk head features a convex curvature. Depending on the type of screw and surface finish (stainless steel, nickel-plated, antique), these screws become a decorative element, for example, in furniture construction or when attaching baseboards.

Unlike partially threaded screws, the full thread extends along the entire length of the screw. The more threads a screw has, the greater the tensile and compressive forces that can be transferred from the screw to the wood. Our full-thread screws are primarily used for high-load wood connections.

The term 4CUT refers to the square shape of the screw tip. These edges displace the wood fibers during insertion and create space for the core diameter of the screw. The spreading pressure exerted by the core in the wood is thus reduced, preventing the wood from splitting near the edges. The necessary torque of the cordless screwdriver is also decreased, as the core of the screw does not have to "squeeze" into the wood.

A nickel alloy is a finishing process that gives the screws a chrome-colored, slightly yellowish appearance. Nickel-plated screws are perfectly suited for indoor use. For outdoor applications, we recommend our screws with WIROX coating for areas not directly exposed to the weather, and for direct exposure, only stainless steel in A2 or A4 quality.
