Spax Chipboard screws

The SPAX typical drive T-STAR plus is a so-called internal hexagon. This shape increases the contact area of our T-STAR plus, allowing the T-STAR plus bits to fit perfectly into the screw head. The optimal power transfer from the screwdriver to the screw through T-STAR plus enables fast work, significantly more efficiently than with any other drives. The countersunk head (or flat countersunk head) carves 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. Unlike 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 high-load wood connections. The S-tip is characterized by the fact that the thread is formed all the way to the front flanks. When you position the screw and start the cordless screwdriver, this thread immediately grips the wood and pulls the screw in effortlessly. This allows for quick work without scratching the workpiece due to the screw tips slipping.
