常见的螺栓与螺母、螺孔联接，其装配的拧紧力矩都有计算方法和推荐值，而双头螺柱的拧紧力矩则少有资料参考。产品工程师参照六角头螺栓计算，作为双头螺柱装配的拧紧力矩，容易出现拧紧力矩过大，拧坏螺牙而产生失效。文章中详细地对双头螺柱装配结构进行分析，并结合装配测试，选取合适的拧紧力矩，解决这类问题。

Normally, it is easy to know the calculate method of tightening torque for bolt/nut assembly, or to get the recommended value. However, such information is rare for stud assembly. During the daily work, product engineer would calculate the tightening torque of stud based on the value of hexagonal bolt, but over-torque issue would be generated and thread will be screwed if such method adopted.In this paper, such kind of issues will be solved by analyzing stud assembly structure, making assembly tests, then proper tightening torques will be selected.
