SPAX universal screw, flange head 6x160/65 T30 Wirox

The typical SPAX T-STAR plus drive is a so-called hexalobular internal drive. This shape increases the contact surface of the T-STAR plus screwdriver and ensures optimal positioning of T-STAR plus bits in the screw head. By enabling maximum power transmission from the screwdriver to the screw, T-STAR plus guarantees simple and exceptionally fast work that is much more efficient than with other drive types.

Unlike partial thread, full thread extends along the entire length of the screw. The more threads a screw has, the greater the tensile and compressive forces these screws can transfer into the wood. Our full-thread screws are primarily used for heavy-duty wood connections.

The term 4CUT refers to the arrow-shaped design of the screw tip. These edges displace the wood fibers as the screw is driven in and create space for the core diameter of the screw. Expansion in the wood core is reduced, which helps prevent the wood from splitting around the edges. The required torque of the cordless screwdriver is also reduced, since the screw core no longer has to "force" its way into the wood.

With WIROX, SPAX has developed a coating that provides significantly better corrosion protection than galvanization. WIROX does not use chromium(VI), which means that even after years in an area not directly exposed to the elements, the screws remain not only just as durable but also completely environmentally friendly. WIROX screws are the ideal choice for all open structures that are not directly exposed to the elements, such as carports and pergolas. For areas directly exposed to weather, such as decks, we recommend our stainless steel screws.
