Spax WIROX T-Star Plus T20 Flooring Screw 4.5mm x 60mm (Tub 300)

The typical SPAX T-STAR plus drive is a so-called hexalobular internal. This shape increases the contact surface of our T-STAR plus and ensures optimal positioning for the T-STAR plus bits in the screw head. By enabling maximum force transmission from the screwdriver to the screw, T-STAR plus guarantees simple and ultra-fast work with much more efficiency than with other drives. The countersunk head (also known as the flat countersunk head) has a polygonal underside ("pockets") that mills its way into the wood and can therefore be countersunk without having to pre-drill the screw hole. The flat countersunk head sits flush with the surface. The fixing thread consists of a main thread, which inserts into the substructure, and another thread below the head. This thread below the head ensures that the board remains securely in place on the substructure in all weather conditions. The smooth shank between the thread parts absorbs the movements of the board. No more re-fastening wooden boards that have become loose or creak too much! The CUT point on our SPAX screws enables the ultra-fast and effective insertion of our wood screws without pre-drilling. In combination with the serrations, the arrow-shaped CUT point reduces wood splitting and tearing. The CUT point also enables extremely precise and sturdy setting of the screw tip on smooth surfaces. With WIROX, SPAX has developed a coating that is far superior to galvanisation when it comes to corrosion protection. No chromium(VI) is used for WIROX, which means that even after years in an area not directly exposed to the elements, the screws are not only just as resilient, but are entirely environmentally friendly, too. WIROX screws are the ideal choice for all open structures without direct exposure to the elements, such as carports and pergolas. For areas with direct weather exposure, such as decking, we recommend our stainless-steel screws.
