13.1.1 Tensile Failure of Bolt. Maximum tensile stress induced in the bolt is given by, where, dc = core diameter of the bolt. Cross-section at core diameter is the weakest section. In addition to this, threads of the bolt can also fail in shear and crushing. For analysing that, it is assumed that each turn of the thread supports equal load and
