Fastening element for securing nut on bolt or screw, has nut and ring elements each comprising recess with internal thread, where threads form pitch error free and pitch errored total internal threads at axial spacing along axis

摘要

The element has a nut element (1) and a ring element (2) each comprising a cylindrical recess (1.1, 2.1) with an internal thread. The recesses are arranged along a longitudinal axis (10) and are axially aligned one behind the other. Two internal threads of the recesses are arranged such that the internal threads form a pitch error free total internal threads at an axial spacing along the longitudinal axis between the nut and ring elements. The two internal threads form a pitch errored total internal threads at the axial spacing along the longitudinal axis.
