Hello, everyone.It is correct that the execution of the Studs were manufactured according to the drawing.Since rain is expected in the next week we ask you to protect all studs in the open area against rain so that no corrosion starts in the holes. We recommend screws and washer.In order to avoid the fixation of stainless steel screws in the thread, "anti-seize" must be used.An example for "Antiseize" is attached.Under no circumstances should grease be used for corrosion protection in order not to hinder the paint build-up in the paintshop.
