The SPAX-typical drive T-STAR plus is a so-called internal hexagon. This shape increases the contact surface of our T-STAR plus, allowing the T-STAR plus bits to fit optimally in the screw head. The best possible power transmission from the driver to the screw through T-STAR plus enables quick work, and it is significantly more efficient than all other drives.

The countersunk head (or flat countersunk head) mills a recess into the wood with its polygonal underside ("pockets") and can therefore be sunk without additional countersinking of the screw hole. The countersunk head sits flush with the surface.

The fixing thread consists of a main thread that is inserted into the substructure and the underhead thread. This underhead thread ensures that the top board is securely held on the substructure under all weather conditions. The smooth shaft between the threaded parts absorbs the movements of the board. You will never have to re-screw wooden boards again because they loosen or creak too much!

The CUT tip of our SPAX screws allows for extremely fast and effective driving of our wood screws without pre-drilling. The arrow-shaped CUT tip, in combination with the wave profile, reduces splitting and tearing of the wood. Furthermore, the CUT tip enables very precise and slip-resistant positioning of the screw tip even on smooth surfaces.

With WIROX, SPAX has developed a coating that is far superior to galvanization in terms of corrosion protection. WIROX does not use chromium (VI), and the screws remain just as durable after years in non-directly weather-exposed outdoor areas, and they are also environmentally friendly. WIROX screws are the first choice for all open structures without direct weather exposure, such as carports or pergolas; for direct weather exposure, such as terraces, we recommend our screws in stainless steel.
