Connection between cast metal part and bolt for joining other components, comprising dead end bore and clawed element

摘要

The cast iron part (1) is provided with one or more dead end bores (4) for joining other components using a bolt (2). In a particularly thin area the bore (4) is created in an elevation. The bolt (2) has a circular head (3) resting on a square element (5) with four axial positioned claws (6) at its outer edge. When the bolt (2) is inserted into the bore (4) the claws (6) are first pressed against the shaft and engage with the inner surface (7) of the bore (4) when the component to be added is secured with a nut (M).
