Spax A2 Senkkopf Bremsrippen T-Star Plus T10 Vollgewinde

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 perfectly into the screw head. The optimal power transfer from the driver to the screw through T-STAR plus enables quick work, and it is significantly more efficient than with any 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.

In contrast to partial threads, the full thread extends over the entire length of the screw. The more thread turns a screw has, the greater the tensile and compressive forces that can be transferred from the screw to the wood. Our full-thread screws are primarily used for highly stressed wood connections.

The S-tip is characterized by the fact that the thread is shaped all the way to the front flanks. When you place the screw and start the cordless screwdriver, this thread immediately grips in the wood and effortlessly pulls the screw in. This allows for fast work without scratching the workpiece due to the screw tips slipping.

The abbreviation A2 in our stainless steel screws comes from the steel alloy. Screws made of stainless steel A2 offer high protection against corrosion and medium strengths. Their resistance to seawater and acids is low. Therefore, they are used in outdoor applications in coastal areas.
