Abstract: There is a tap having a tapered threaded portion 2 whose thread teeth 4 located in the tapered section are provided with a relief arranged at a clearance angle. It is desirable that the cutting moment and friction should decrease to the back towards the greater diameter. This is achieved in that the clearance angle of the thread teeth 4 in the tapered section 2 remains constant or increases towards the back. A simple machining measure permits the cutting moment and friction to be variably controlled over a wide range.

Abstract: An arrangement for closing a cable socket for connecting and branching cables, particularly telecommunication cables.
