Spax Chipboard screws SK T30 6,0x80 mm

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 efficiently than with any other drives. The countersunk head (or flat countersunk head) carves a recess into the wood with its polygonal underside ("pockets") and can therefore be sunk without additional countersinking of the screw hole. The countersunk head sits flush with the surface. The screws with partial thread are excellently suited for fastening thin components such as wood-based panels, boards, or floorboards to thicker components like beams or joists. 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 equal to the thickness of 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 screw's core diameter. 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 be "squeezed" 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 and environmentally friendly even after years in outdoor areas not directly exposed to the elements.
