粗螺纹VS细螺纹
粗螺纹和细螺纹哪个好？这是相对于螺纹护套和外螺纹紧固件而言，在KATO技术集团经常听到的问题，KATO认为，粗螺纹比细螺纹有很多优势和好处。
概要
通常，除非有令人信服的理由，否则大多数工业应用都指定使用粗螺纹。军事和航空航天应用一般使用8-32及以下尺寸的粗螺纹。在公制紧固件上，通常最常用的是粗螺纹，而较细的螺距则不容易获得。
细螺纹
细螺纹螺栓比同等硬度的相应粗螺纹螺栓强度高。这是在拉伸和剪切力方面，由于细螺纹螺栓具有稍大的拉应力区域和小直径。
由于细螺纹的螺旋角比粗螺纹小，所以在振动下松动的可能性较小。细螺纹锁紧插入式握紧盘比粗螺纹插入式相应尺寸的握紧盘更有弹性，在振动条件下不易采取套。
细螺纹由于其更细的螺距，在那些需要这种特性的应用中可以进行更精细的调整。
细螺纹可以更容易地攻入难以攻入的材料和薄壁部分。
细螺纹需要较小的紧固力矩，以形成与相应粗螺纹螺栓尺寸相当的预紧力。
