Abstract
A fastening screw is used to hold a hollow body against a base body. To assure that no dirt can get into the hollow body, sealing between the fastening screw and the hollow body is necessary. The fastening screw has a bevel (10s) coated with a relatively soft coating at the transition between the screw shaft and the screw head. When the fastening screw is tightened, one edge of the hollow body digs into the coating, thus assuring a secure seal. The fastening screw is intended in particular in a brake system for securing a motor housing to a pump housing.
