Screw with self-locking thread

The normal thread (17) has an equilateral triangle- section with a sharp tip (18) and flat sides (19,20). Each turn of the thread is separated by a flat base portion (13). Several lengths of the thread are modified, with a gradual lead-in from the normal thread, to make locking threads (5). The tip...

Zusammenfassung:	The normal thread (17) has an equilateral triangle- section with a sharp tip (18) and flat sides (19,20). Each turn of the thread is separated by a flat base portion (13). Several lengths of the thread are modified, with a gradual lead-in from the normal thread, to make locking threads (5). The tip of the thread is flattened (21), the upper parts of the sides are bulged outward (22,23), and the mid-portions (26,27) have a steeper slope leading to pushed-inwards lower portions (24,25).
