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.

In contrast to the countersunk head, which is designed flat to enable flush screw countersinking, the raised countersunk head has a convex shape. Depending on screw type and surface material (stainless steel, nickel-plated, antique), these screws can be used as a decorative element in furniture construction or for fastening skirting boards.

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 term 4CUT stands for the arrow-shaped design of the screw tip. These edges displace the wood fibres upon insertion and create space for the core diameter of the screw. The expansion at the core of the wood is reduced, preventing 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.

With our stainless-steel screws, the abbreviation A2 refers to the alloy of the steel. Screws made of stainless steel A2 offer a high level of protection against corrosion and medium strength. However, they have low resistance to saltwater and acids. They are therefore used in outdoor applications in non-coastal areas.
