SPAX general-purpose screw, flange head 6x80/61 T30 A2

The typical SPAX T-STAR plus drive is a so-called internal hexalobular design. 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 ensures simple and extremely fast work much more efficiently than with other drive types.

Partially threaded screws are ideally suited for fastening thin components, such as wood-based panels, paneling, and floorboards, to thicker components such as rectangular timber beams or joists. 

The short thread penetrates the thick component, while the unthreaded shank remains in the fastened part. This creates maximum clamping pressure between the two. The unthreaded section should be at least as thick as the fastened part.

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 screw core diameter. Expansion of the wood core is reduced, which helps prevent splitting around the edges. The required torque of the cordless screwdriver is also reduced, because the screw core no longer has to "force" its way into the wood. In our stainless steel screws, the abbreviation A2 refers to the steel alloy. Screws made of A2 stainless steel offer high corrosion protection and medium strength. However, their resistance to saltwater and acids is limited. Therefore, they are used outdoors in non-coastal areas.
