WebA bolt attached to a plate experiences shear stress when the ends of the plates are subjected with shear force. The shear stress acting on the bolt is given as below- where, t1 and t2 are thicknesses of plates (for two plates) d is the nominal diameter of the bolt How to shear stress from normal stress? WebThe bolt grade determines the maximum amount of stress the bolt can handle. Tensile strength is the amount of pull the bolt can withstand before breaking. The method used for tightening the bolt is dependent upon the bolt grade. The grades are indicated on top of the bolts. They show up as raised numbers or dashes.
