Calculate bolt thread engagement length
WebOct 10, 2011 · How can I calculate the thread strength depending of the length of engagement of a bolt in a metal plate? More precisely, I want to ensure that a 3/4-10 bolt won’t shear out the threads of the 1in thick plate in wich it is screwed. The plate material tensile strengths are : Ultimate : 78ksi Yield : 44ksi Also the shear modulus is 11600ksi.
