Spax Chipboard screws A2

The SPAX typical drive T-STAR plus is a so-called internal hexagon. This shape increases the contact area, allowing the T-STAR plus bits to fit optimally in the screw head. The best possible power transfer from the screwdriver to the screw through T-STAR plus enables quick work, significantly more efficient than with any other drives.

The countersunk head (also known as 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 extends into the front flanks. When you position the screw and start the cordless screwdriver, this thread immediately grips in the wood and effortlessly pulls the screw in. This allows for quick work without scratching the workpiece due to the screw tips slipping.

The abbreviation A2 in our stainless steel screws comes from the alloy of the steel. 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 for outdoor applications in coastal areas.
