Welding screws for automotive sector

In the automotive industry the welding screws are mainly used to fix the various components to the body of the car. They are mostly produced with indentations above and below the head that melt down during the welding process and ensure a tight seal. The installation is usually done with a capacitor discharge and the aesthetic quality of the application doesn't change as the opposite side of where the screws are welded remains smooth. The assembly does not necessarily require access from both sides of the sheet.
