Also known as a double cross or Pozidriv, the cross recess Z is a further development of the cross drive by the Phillips Screw Company. The difference is that the four flanks of the screwdriver blade do not taper towards the tip. This increases the lateral hold for the screwdriver bit and reduces the so-called cam-out effect. This occurs through the typical tapering on conventional cross drives, since the torque exerted by the cordless screwdriver pushes the bit upwards and out. What this means for you: No more worrying about screwdriver bits slipping out, easier work with much less exertion. This saves a huge amount of time.
Of all of our head shapes, the raised countersunk head is undoubtedly the most attractive. In contrast to the countersunk head, which is designed completely flat to enable flush countersinking, the raised countersunk head has a slightly convex shape on top. Depending on screw type and surface material (stainless steel, nickel-plated, WIROX and antique), these screws not only function as a necessary fastener, but also as a decorative element. This is important in tasks such as furniture construction or fastening skirting boards. What this means for you: No need to countersink screw heads or waste time camouflaging screw holes in visible areas of furniture and skirting.
In contrast to the partial thread, the full thread on most of our full-thread screws covers the entire – or most of – the screw length from tip to head. The more thread turn a screw has, the greater the tensile and compressive forces that can be absorbed by these screws. We make particular use of this in structural wood construction, where our full-thread screws are called upon for heavy-duty wood connections. What this means for you: Wood connections with full-thread screws offer maximum reliability when it comes to resilience, and there's no need to use any ugly zinc-plated fittings!
The term 4CUT is used to describe the fact that the point of our screws is not rounded, but rather shaped like an arrow. These four edges displace the wood fibres upon insertion and thus create space for the core diameter of the screw. The otherwise inevitable expansion at the core of the wood is effectively reduced, minimising wood splitting around the edges. The required cordless screwdriver torque is also reduced, since the screw core no longer needs to ""squeeze"" into the wood. What this means for you: Practically no pre-drilling required any longer – even in the edge areas of your workpiece that are normally prone to splitting! The 4CUT means you can skip an entire work step.
Nickel plating is a screw refining process. This protects the steel screw against corrosion and gives it a chrome-coloured, slightly yellowish finish. Nickel-plated screws are perfect for use in indoor areas with no direct exposure to the elements. For outdoor areas exposed to the elements, we recommend our WIROX-coated screws in stainless steel A2 or A4. What this means for you: High level of corrosion protection indoors at an optimal price.
