Spax Wood construction screw R 88192 Cylinder head T-STAR 6 x 60/28 -T A 4 w.CUT-Sp.

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 transmission from the screwdriver to the screw through T-STAR plus enables quick work, and it is significantly more efficient than with any other drives.

The screws with partial threads are excellent for fastening thin components such as wood-based panels, boards, or floorboards to thicker components like beams or posts. The short thread screws into the thick component, while the unthreaded shaft remains in the attachment. This creates maximum clamping pressure between the two. The unthreaded part should be at least as thick as the attachment.

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 core diameter of the screw. The spreading pressure exerted by the core in the wood is thus reduced, preventing the wood from splitting near the edges. The necessary torque of the cordless screwdriver is also reduced, as the core of the screw does not have to "squeeze" into the wood.

With WIROX, SPAX has developed a coating that is far superior to galvanization in terms of corrosion protection. WIROX does not use chromium (VI), and the screws remain just as durable even after years in non-directly weather-exposed outdoor areas, and they are also environmentally friendly. WIROX screws are the first choice for all open structures without direct weather exposure, such as carports or pergolas; for direct weather exposure, such as terraces, we recommend our screws in stainless steel.
