Abstract: Plies have a first and a second plier limb which are rotatably held relative to one another on an axis of rotation an articulation region and form a jaw region on one side of the articulation region and handle sections on the other side of the articulation region. The jaw region has a cutting pattern with first and second cutting edges which, in the closed position of the pliers, are crossed with respect to a shear plane and which have a central plane running through the axis of rotation, perpendicularly to the shear plane in the closed position. The cutting edges are crossed to a greater degree in a region remote from the articulation, in the opening direction of the pliers, than in a region closer to the articulation.

Abstract: Provided is a nut and a bolt tightening method for fastening an object, wherein a tightening force is applied on the object by rotating a nut or a bolt in a state in which a predetermined tension force is applied on the bolt in the axial direction of the bolt. When the tensile force exerted on the bolt decreases as the tightening force increases and after a timing when an inflection point occurs in a time course change in a ratio of an amount of change in the tensile force exerted on the bolt to an amount of change in an angle of rotation of the nut or the bolt, the tightening resulting from the rotation of the nut or bolt is terminated and the tensile force applied on the bolt is removed.
