Abstract
A washer has a body having an axis and provided with a first face surface located at one axial side and adapted to cooperate with a nut, a second face surface located at an opposite axial side and adapted to cooperate with an object to be assembled or disassembled, and at least one additional turning resistant surface adapted to cooperate with a bolt, the additional turning resistant surface of the body being formed as a frictional surface providing a friction between the body and the bolt to frictionally impede the bolt from turning and at the same to allow the bolt to be displaced in an axial direction when the nut is turned, the second face surface of the body being formed to provide a friction between the body and the object and therefore to impede the body from turning, and the first face surface of the body being formed with a smaller frictional characteristic than the second face surface of the body to at least reduce dragging of the body into turning by the turning nut; and a fastener is provided with such washer.
