Spax Senkmultikopf T-Star Plus T50 Teilgewinde

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 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 (or flat countersunk head) mills a recess into the wood with its polygonal underside ("pockets") and can therefore be sunk without the need for 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 high-load wood connections.

The CUT tip of our SPAX screws allows for extremely fast and effective driving of our wood screws without pre-drilling. The arrow-shaped CUT tip, in combination with the shaft profile, reduces splitting and tearing of the wood. Additionally, the CUT tip enables very precise and slip-resistant placement of the screw tip even on smooth surfaces.

Stainless steel screws A4 can do everything that an A2 stainless steel screw can do. However, the higher alloy also makes these screws resistant to acids and seawater. These screws are primarily used in coastal regions. Since chlorinated water contains acid, you should also use stainless steel screws A4 if you are planning a wooden deck around a garden pool.
