Abstract
A screwed connection has a first connecting means with an external thread and a second connecting means with an internal thread. In order to avoid self-slackening of the screwed connection, the external thread has a denticulation (14-16) which interacts with a mating denticulation of the internal thread.
Claims21
A screwed connection with an internal thread, having at most one thread turn, characterized in that the connecting means (131) is part of a sheet-like material (132), the sheet-like material having material reinforcement (142) in the region of the internal thread (138), in which material reinforcement (142) the thread turn is embossed.
The connecting means as claimed in claim 18, characterized in that the material reinforcement (142) consists of displaced material of the sheet-like material.
A method of incorporating an internal thread in a sheet-like material (132), characterized in that, in a first step, the sheet-like material (132) is pierced, the material displaced by the piercing being arranged laterally in the form of a turned-out portion (141), in that, in a second step, the turned-out portion (141) is made more uniform to form a collar (142), and in that, in a third step, a thread turn (133) is embossed with the collar (142) being deformed.
