Zelftappende schroef

The Cobalt self-tapping screw (art. 6112625) is the fixing screw of the Cobalt flat-roof system. According to the flat-roof manual, the back plates are fixed with these screws at a torque of 8 Nm, and ballast containers and ballast trays are screwed between two supports at more than 6 Nm, which also fixes the row spacing. Install with an SW10 socket. In the 2026 Cobalt manuals this screw has been succeeded by the thin sheet metal screw 6 x 25 mm (art. 6516025). The number of screws follows from the CoBuilder bill of materials. Warranty: 20 years under the Cobalt warranty conditions.
