下表显示的是对绝大多数的常规螺丝拧紧时，建议采用的扭矩值。对于未经处理的浸油螺丝（摩擦系数=0.125）进行操作时，推荐采用大拧紧扭矩（N.m）。公用粗牙螺纹，扭矩对应大致62% 的拉伸载荷。

The following table shows suggested torque value for general bolt and screw tightening. Maximum torque is suggested to adopt for operating immersion oil screw (friction coefficient=0.125) without treatment.
