The SPAX-typical T-STAR plus drive is a so-called Torx socket. This shape increases the attack surface in our T-STAR plus, and the T-STAR plus bits fit optimally in the screw head. The best possible power transfer from screwdriver to screw by T-STAR plus enables a fast working, and much more efficient than with all other drives.
When it comes to furniture, nails offer only little resistance to retraction for the rear wall in the edges of the body. Here we have the better alternative with our flat-back bolt because the large flat head distributes the pressure over a larger area. The flat-back bolt head screws for the body connection replaces the screw/sleeve combination: They are screwed into the 5 mm euro holes, self-centered and pulls both bodies tightly together. The head of the body screws is not in the way of cabinet installations such as drawer trays.
The screws with partial thread are extremely suitable for attaching thin components such as wood material plates, boards or boards to thicker components such as square timber or beams. The short thread screws into the thick component; the thread-free shaft remains in the attachment part. This gives rise to the maximum contact pressure between the two. The thread-free part should be at least equal to the thickness of the attachment part.
The term 4CUT stands for the square shape of the screw tip. These edges supplant the wooden fibers during insertion and creates space for the core diameter of the screw. This reduces the spread pressure exerted by the Kern in the wood and prevents the wood from springing up close to the edges. The necessary torque of the cordless screwdriver is also reduced, because the Kern of the screw does not have to "squeeze" itself into the wood.
A nickel alloy is a finishing process in which the screws have a chrome-colored, slightly yellow appearance. Nickel plated screws are perfect for indoor use. In the outdoor area, we recommend our screws with WIROX coating if not directly wetted, but in direct weather only stainless steel A2 or A4 quality.
