Joining assembly including a plastic support member and a plastic threaded element |
摘要 |
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.
