The FLATHEAD® 4.2x13 mm self-drilling screw is the first connector of its kind on the market for thin walls and load-bearing steel elements in plasterboard systems. It allows to simply and unrestrictedly create complex shapes based on plasterboard panels. Due to the unique shape of the screw head, there is less work required in mounting the cover and finishing the surface, which is reflected in low production costs. The head is flattened almost to the maximum (approx. 1 mm) to prevent deformation of the plasterboard sheathing during the mounting process on the previously prepared structures.
