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.

Installing window and door frames with plastic and aluminium profiles calls for a head shape that can withstand high pulling forces whilst not being too thick. Our flat countersunk head ticks both boxes. It finds its place on our SPAX-RA full-thread screw, which is used for the plug-free fastening of window and door frames. As you might expect, the T-STAR plus drive takes care of force application. What this means for you: No more obstructive screw heads inside window and door frames.

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.

YELLOX is our SPAX innovation when it comes to corrosion protection, which not only benefits you as the user, but also the environment. Unlike the conventional yellow or blue zinc-plated screws, YELLOX ist chromium(VI)-free and is therefore much better for humankind and nature alike. They are also just as resistant to corrosion as their conventional zinc-plated counterparts with the same surface thickness. However, their use is limited to indoor areas. As the name suggests, YELLOX-coated screws also have a yellowish appearance. What this means for you: You can fasten with YELLOX screws indoors without hesitation – harmful chromium(VI) and corrosion are a thing of the past.
