WebBy merely ensuring that the shear load is applied to the body of the bolt, the shear strength can improve by 8,260 pounds. On the other hand, if the application calls for the shank to be in the shear plane, substituting a Grade 5 (with its longer thread length) would place the threads in the shear plane, resulting in an 8,260 lbs. reduction in shear strength.
