Screws, bolts and nuts are locked.

Sealing is achieved thanks to internal and external shoulders (the internal shoulder goes into the thread of the screw and the external one fits around the head of the screw / nut).

Absorbs vibrations, corrosionresistance, protection against electrolytic action and protection of the surface of materials to be assembled.

Perfect insulation and security.
