A threaded fastener has a bolt (1), nut means including a sleeve (3) with which the bolt (1) is screw-threadedly engaged and a washer (5) having a lower bearing surface adapted to bear on a surface of one of at least two elements (2,2') to be connected together by the threaded fastener. The washer (5) is press-fitted 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 (5) does not turn and the bolt (1) also does not turn but moves only in an axial direction.
