• Heavy-Gauge Drilling: The integrated mini-drill point allows the screw to easily penetrate thicker steel profiles (up to 2.0 mm thickness) without walking or the need for pre-drilling.

• Thread Engagement: Features a fine thread pitch optimized to lock tightly into structural steel studs and metal frame systems.

• Phosphate Protection: Special surface treatment prevents rust bleeding through finished decorative paint or plaster.

Application Range:

Fixing single-layer drywall sheets, reinforced plasterboards, or structural paneling to heavy-duty, thick metal stud partitioning and structural steel framing profiles.
