*Note
The self-drilling screw JT3-X-2-6,0xL is a product approved by the building authorities for fastening clips to substructures made of steel, wood or aluminium. Each clip must be fastened with 2 screws in the shape shown below. The special feature of the screw is in the brake ribs under the head. These are able to greatly increase the over-torque, which is reflected in an increase in assembly safety. In arrangement 1, sealing washers must be used.
