摘要

A fastening device for joining together mechanical parts is provided, where the fastening device includes integrated cutting edges that are so arranged, during assembly of the fastening device, as to remove material from the envelope surfaces of the assembly hole by cutting in a rotating movement, so that the assembly hole is caused to fit the envelope surface of the fitting part. A fastening device can be provided which, by simple and inexpensive means, is so arranged as to absorb both shearing loads and tensile/compressive loads arising between the joined parts.
