Spax Chipboard screws A2

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.

Where the countersunk screw is flatly designed for flush sinking of the screws, the lens countersunk head features a convex curvature. Depending on the type of screw and surface finish (stainless steel, nickel-plated, antique), these screws become a decorative element, for example, in furniture construction or when fastening baseboards.

In contrast to partial threads, 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 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 extends into 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.

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 strength. Their resistance to seawater and acids is low. Therefore, they are used in outdoor applications in coastal areas.
