Abstract
A threaded fastener has a bolt, a nut including at least one sleeve in which the bolt is threadingly engaged, and a washer having a lower bearing surface adapted to bank on a surface of one of at least two elements to be connected with one another by the threaded fastener, the washer being pressed-fit on a part of the threaded fastener, so that when an active force and an opposite reactive force are applied to parts of the threaded fastener, the washer does not turn, while the bolt also does not turn but moves only in an axial direction.
