    • A bolt fastening method enabling the same effect as when reducing the coefficient of friction of a thread surface without changing the coefficient of friction of the thread surface so as to realize an increase in a bolt axial force generated when fastening the bolt and a bolt fastening device realizing the bolt fastening method are provided.The bolt fastening method of the present invention is a bolt fastening method for when using a bolt having a bolt head and a bolt shank provided with an external thread to fasten fastened members, characterized by intentionally biasing surface pressures of a thread surface and a bolt bearing surface generated when fastening the bolt by imparting a lateral load parallel to the bolt bearing surface to the bolt head and, in that state, imparting a rotational torque rotating the external thread to the bolt head so as to fasten the bolt.
    • 一种螺栓紧固方法,其能够在不改变螺纹表面的摩擦系数的同时降低螺纹表面的摩擦系数而实现相同的效果,以实现当紧固螺栓时产生的螺栓轴向力的增加和螺栓紧固装置 提供螺栓固定方法。 本发明的螺栓紧固方法是一种螺栓紧固方法,用于当使用具有螺栓头和设置有外螺纹的螺栓柄的螺栓来紧固紧固构件时,其特征在于有意地偏压螺纹表面和螺栓轴承的表面压力 通过向螺栓头施加平行于螺栓支承表面的横向载荷来紧固螺栓时产生的表面,并且在该状态下,赋予将外螺纹旋转到螺栓头的旋转扭矩,以便紧固螺栓。
