The image is deliberately chosen in my opinion as to deceive the consumer. On display are namely the fortifications of the screw thread. In the delivery but they are not included. And for me as the borrowing are not familiar with the terms, it was not the same to realize that not, are also included in the delivery all the items that are on the screen. Otherwise I would not order the items. Thus, I am disappointed, although the description was correct. HALT is not everything. The Gesamteindrung does it. LG
