SEALING BY MATERIAL DEFORMATION.

摘要

The invention relates to a method for producing a sealing arrangement between an opening (26) of the support (4) bore (25) and a screw (17) which comprises a head connected to a body and is provided with a threaded section for interacting with the hole of a part to be assembled with a support (4) whose mechanical strength is lower than that of the screw. Said invention is characterised in that, starting from an enlarged opening, the inventive method consists in engaging the screw into the bore (25) in such a way that the head thereof is brought into contact with the opening (26), in screwing said screw into the hole of the part to be assembled in such a way that a pressure applied by the head sealingly presses the opening against the part of the under-head surface (27) of the screw by removing a part of material of the support (4).
