Generally, the price of high-strength bolts will be much higher than that of ordinary bolts. If the shear stresses on the bolt cannot be avoided bushings should be used to have the tensile stresses carried by the bolts and the shear stresses carried by the bushing.

This means they must be installed and torqued so highly that they approach their yield point, sometimes very closely.
