Abstract
A fastening element is provided for connecting mechanical parts to one another. The fastening element includes integrated, cutting machining grooves which are designed to work the edges of the hole, during fixing of the fastening element, by the removal of material in the parts to be mutually connected, so that the hole is made to fit against the shell surface of the fastening element. A fastening element can be provided which, in a cheap and simple manner, is designed to absorb both occurring shearing loads and compression/traction loads between the connected parts.
Claims20
A fastening element for connecting mechanical parts to one another comprising:
- a pin-shaped lead-through part adapted to extend through a hole running continuously through at least one of the parts to be mutually connected;
- and
- a head having a contact surface for bearing contact against a contact surface on one side of the hole, the lead-through part having a fitting part adapted to extend through the hole, and a fastening part of a diameter which is less than the diameter of the hole and is adapted to fasten in a fastening component, wherein the fitting part has a diameter which is greater than a diameter of the hole, in its state prior to fixing of the fastening element, and the fitting part has cutting machining grooves which are adapted to work edges of the hole, during fixing of the fastening element, by removal of material such that the hole is made to fit against a shell surface of the fitting part, the fastening element being adapted to absorb both occurring shearing loads and compression/traction loads between the connected parts.
