SPAX 0207000350203 R 88093 Ruko m.Spitze/T-STAR VG Roundhead wood screw 3.5 mm 20 mm T-Star Plus Stainless steel A2 200

The SPAX-typical T-STAR plus drive is a so-called Torx socket. This shape increases the attack surface in our T-STAR plus, and the T-STAR plus bits fit optimally in the screw head. The best possible power transfer from screwdriver to screw by T-STAR plus enables a fast working, and much more efficient than with all other drives.

Our universal screw with round head (Panhead) is an example of how screw connections can look good if necessary. The spherical screw head with T-STAR plus or Z cross-head drive is suitable for the visible attachment of metal fittings on wood, the bottom of the head lies flat on the metal. The WIROX surface fits the color of the silver metal fittings.


In contrast to the partial thread, the full thread extends over the entire length of the screw. The more threads a screw has, the greater the tensile and compressive forces that can be deflected from screw to wood via it. Our threaded screws are used mainly for high-strength wood joints.

The term 4CUT stands for the square shape of the screw tip. These edges supplant the wooden fibers during insertion and creates space for the core diameter of the screw. This reduces the spread pressure exerted by the Kern in the wood and prevents the wood from springing up close to the edges. The necessary torque of the cordless screwdriver is also reduced, because the Kern of the screw does not have to "squeeze" itself into the wood.

The abbreviation A2 on our stainless steel screws is based on the alloy of HER steel. Screws in the stainless steel version A2 offer high protection against corrosion and medium strength. Low is their resistance to seawater and acids. For this reason, they are screwed in outdoor areas that are far from the coast.
