Abstract

A quick fastener by means of which at least a first and a second component are connectable to each other. The quick fastener includes a fastening bolt having a fastening thread of a first spiral direction, which is fastenable at the second component, and a compressible pretension element which is fastenable at the first component. The compressible pretension element includes a pretension thread at a radial inner side having a second spiral direction opposite to the first spiral direction, a hollow cylindrical thread element which is screwable with an outer thread at a radial outer side into the pretension thread of the pretension element having an inner thread at its radial inner side into which the fastening thread of the fastening bolt is screwable. At least a constructive rotation protection is provided between the hollow cylindrical thread element and the compressible pretension element. A production method for the quick fastener is further provided.
