The advantage of this type is the screw-in "self-cutting" fit. Thanks to its threaded sleeve, it works independently of the screw thread, e.g. trapezoidal, buttress, imperial or metric and of the shape of the nut, e.g. round or hexagonal.
The entire screw connection is protected, from U-plate to nut to screw projection.
The self-cutting threaded sleeve offers an extremely safe and completely solid support.
The application: screw connections with large threaded end, e.g. for hydraulically tensioned connections.
