Abstract
In order to provide a pin for connecting machine parts with one another, which is of optimally light weight, the pin is of a compound structure comprising a core of filler-reinforced synthetic plastics resin and a metallic envelope. As filler there are used quartz sand or carbon fibers. The envelope is preferably seated on the core under circumferential tensile bias. The manufacture of the pin takes place, for instance, by pressing the filler and a matrix resin system directly into a suitably prepared envelope.
