The only true girdle system. It does not bolt the cylinder to the cases, but sandwiches the cylinder between the head and the cases. Therefore, there is no pressure on the base of the cylinder.

Cutting threads leaves the root of the thread sharp, weakening the thread and making them easier to break.
