SPAX 0251010500775 Wood screw 5 mm 77 mm T-Star Plus Steel WIROX 150 pc(s)

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.

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.

With WIROX, SPAX has developed a coating that is far superior to zinc plating in terms of corrosion protection. With WIROX no chrome (VI) is used, the screws can be loaded just as well after years in the not directly weathered external area as well as environmentally friendly. WIROX screws are the first choice for all open buildings without direct weathering such as carports or pergoles, for direct weather stresses as with terraces we recommend our screws in the stainless steel version.
