This calculator assumes standard bolt holes, with members stressed only in shear (i.e., with no tension resisted by the bolts). Bolt capacity is based on the smaller of bolt shear and material bearing capacities, and, if desired, is adjusted based on bolt spacing (i.e., reductions in capacity are possible when bolt spacing is less than optimal).
