| 摘要 |
The present invention relates to a screw nut (10) for limiting an acting torque and a method corresponding thereto. The screw nut (10) has a threaded section (1) and a tubular section (2), where a predetermined breaking point (3) is arranged between the threaded section (1) and the tubular section (2), and where the threaded section (1) has a first shoulder structure (6) for a wrench and the tubular section (2) has a second shoulder structure (7) for an additional wrench. The screw nut (10) according to the invention preferably consists of a synthetic material, in particular of a polymer such as polyamide. This has the advantage that particularly the region of the predetermined breaking point (3) may consist of a material differing from, in particular softer than, the threaded section (1) and/or the tubular section (2), and therefore a defined torque limitation is obtainable not only via the geometry of the predetermined breaking point (3) but also or exclusively via selectively processed material of suitable quality.
