Abstract: Thread lock for a threaded connection between a nut body composed of plastic with a nut thread and a bolt with a bolt thread, of which the bolt thread is a standard outer thread of a specified tolerance class with a degree of tolerance and a tolerance zone position, and the nut thread is modified compared to the standard inner thread assigned to the standard outer thread, such that a) the maximum size of the outer diameter of the nut thread lies within the tolerance zone of the outer diameter of the bolt thread, and b) the pitch of the nut thread is changed relative to the pitch of the bolt thread by such an amount that the deformation of the nut body created hereby remains within a permissible range.

Abstract: A threaded element of plastic material for a joining assembly has a uniquely formed thread profile of a small profile angle between 30° and 50° and a rounded crest of a relatively large radius of curvature. The gap between the revolutions of the thread is of a volume which exceeds that of the thread. In order to provide for a specific cutting geometry of the thread profile the threaded element comprises a plurality of angular segments which are radially offset with respect to each other such that adjacent angular segments provide cutting edges. Furthermore, a tool and a method for making such a joining assembly are disclosed.
