How do you calculate the shear strength of a bolt?

  1. Shear Stress Equation Single Shear. Shear Stress Average = Applied Force / Area. or. Shear Stress ave.= F/( π r 2)
  2. Bearing Area Stress Equation for Plate and Bolt or Pin. Bt= F / (t d) Where:
  3. Factor of Safety. Factor of Safety = F.S = ultimate stress / allowable stress. Therefore:
