Abstract:
A washer (6), to be applied between a nut (3) threadingly connected with a bolt (1) which has an axis (A2) and an object (2) including at least two parts to be assembled, has a body (7) having an axis (A1) and is provided with a first bearing face surface (8) located at one axial side and adapted to cooperate with the nut (5), and a second bearing face surface (9) located at an opposite axial side and adapted to cooperate with the object (2). At least one third turning resistant surface (10) of the washer (6) is adapted to cooperate with a thread of the bolt (1), so that when the nut (3) is turned with a given torque in one direction and the body (7) of the washer receives simultaneously the given force in an opposite direction, only the nut (3) turns to tighten or loosen the bolt (1) while the body of the washer and the bolt remain rotation stationary. A new method and a new power tool can be employed to use the new washer.
