Spax Fassadenschrauben LK A2,4.5x60mm

The SPAX typical drive T-STAR plus is a so-called internal hexagon. This shape increases the contact surface 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, and it is significantly more efficient than with all other drives.

Where the countersunk screw is designed flat for flush sinking of the screws, the pan head screw 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.

The fixing thread consists of a main thread that is embedded in the substructure and the underhead thread. This underhead thread ensures that the top board is securely held on the substructure under all weather conditions. The smooth shaft between the threaded parts absorbs the movements of the board. You will never have to re-screw wooden boards again because they loosen or creak too much!

The term 4CUT refers to the square shape of the screw tip. These edges displace the wood fibers during insertion and create space for the screw's core diameter. The spreading pressure exerted by the core in the wood is thus reduced, preventing the wood from splitting near the edge. The necessary torque of the cordless screwdriver is also reduced, as the screw's core does not have to "squeeze" into the wood.

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