Partially Threaded Wood and Chipboard Screw with SIT Drive

The 6x90 mm screw with SIT drive is a dedicated solution for assembly in wood and chipboard, where precision, stability, and minimal material damage are critical. Made from blue galvanized steel, it features a partial thread that reduces wood splitting forces – especially when installing near edges or in delicate components such as door or window frames.

The SIT drive not only ensures fast and secure installation but also eliminates the risk of the screw camming out during driving. The conical recess allows for natural tool centering – no need to apply pressure or adjust the angle. This significantly reduces physical effort and minimizes the risk of bit tip damage. Compared to TX bits, SIT offers superior torque transmission and longer tool life.

A sliding coating further reduces friction – resulting in lower torque requirements during installation. The outcome? Extended battery life for cordless screwdrivers and reduced risk of motor burnout under intensive use.

Beneath the screw head, external milling ribs ensure uniform fastening and minimize wood shavings on the surface – ideal for final elements where aesthetics matter. No additional sanding or cleaning of the installation area is required.

The product holds ETA-12/0198 approval, meaning it has been verified as safe and effective for construction applications – not only for furniture but also for wooden structures in building construction. This is not just a standard furniture screw; it meets construction standards.

A single SIT bit accommodates four different screw diameters – simplifying storage and on-site assembly. There is no need to change bits when switching from 5 mm to 6 mm screws; simply change the screw itself.

The screw is suitable for both wood-to-wood and wood-to-chipboard assemblies – ideal for installers working on doors, windows, kitchen furniture, or frame structures.
