(EMC = Electro-Magnetic Compatibility)

1. Purpose

EMC SCREWS are used in the Bonding/Riveting repair method to re-establish bonding transition.
They assume the function of welded joints, which ensure transition to ground between the individual components.
The punch or blind rivets used in the repair do not guarantee permanent bonding transition between the individual components!
The EMC screws ensure the operational reliability and safety of the electrical/electronic components following repairs!

2. Procedure, aluminium front end

Each welded joint which is opened must be replaced by at least 2 EMC screws.
Position the 2 screws on the flange on which the weld seam has been separated. In the event of partial replacement, position the screws in the area of the component overlap.
In the case of repairs using partial replacement, the number of EMC screws described in the repair instructions must be fitted.
Drill holes to a diameter of 4.2 mm and insert screws.
Seal EMC screws with PU sealing material (risk of corrosion).

3. Procedure, steel body

Install the number of EMC screws described in the repair instructions.
Drill holes to a diameter of 4.2 mm and insert screws.
Seal EMC screws with PU sealing material (risk of corrosion).
