Witryna23 lis 2015 · except that the thread engagement need not exceed 1.5 d s. I have always used the rule of thumb that the bolt has to be engaged at least one bolt diameter. This partly comes from looking at structural nuts. Structural nuts develop the full strength of the bolt in tension. These nuts typically engage about one bolt diameter. WitrynaThe following equation is used to calculate the minimum Thread Engagement Length. Le = 2*At / ( .5*pi* (D-.64952*p)) Where Le is the minimum thread engagement length (in) At is the tensile stress area (in^2) D is the diameter of the screw (in) p is the thread pitch = 1/number of threads per inch

Our Supplier is stating their results are 9.2~9.5. From my measurements I am seeing 8.2~8.5 So some are undersized, or just at min. And of course, measurement method is playing a role in this scenario. I just want the measurements to be accurate and go from there.
