Abstract
A hydraulic camshaft adjuster for an internal combustion engine. The hydraulic camshaft adjuster has a drive part that can be drive-connected to a crankshaft, an output part which has a central, first axial opening for the rotatably fixed connection to a first camshaft and is mounted such that it can be adjusted rotatably with respect to the drive part, a hydraulic actuating mechanism, by which a rotary angle position between the drive part and the output part can be adjusted, and a screw plug which is screwed to the drive part for closing the first axial opening. The screw plug is manufactured from a shaped part which is produced by a forming process without the removal of material.
