41 00... EMC Screws

(EMC = Electro-Magnetic Compatibility)

1. Purpose: 
   • EMC screws are used in the Bonding/Riveting repair method to re-establish bonding transition. See 41 00... OVERVIEW OF CONSUMABLES  (7.0 EMC screw (electromagnetic compatibility)).
   • 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, aluminum 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).
