    This document provides bolt capacities for non-preloaded ordinary bolts made of S275 steel. [1] It includes the tensile stress area, tensile capacity, shear capacity, and bearing capacity for bolts of various diameters from 6mm to 30mm and grades 4.6 and 8.8. [2] Notes provide additional information on clearance hole sizes, how the tension capacities account for prying forces, and multiplication factors to apply if oversized or slotted holes are used. [3] Shear capacities may also need reduction for large packings, grip lengths, or long joints.

    NOTES:
    . 2 mm clearance holes for f < 24 or 3 mm clearance holes for f < 24.
    . Tabulated tension capacities are nominal tension capacity ¼ 0.8A p which accounts for prying forces.
    t t
    . Bearing values shown in bold are less than the single shear capacity of the bolt.

    . Bearing values shown in italic are less than the double shear capacity of the bolt.
    . Multiply tabulated bearing values by 0.7 if oversized or short slotted holes are used.
    . Multiply tabulated bearing values by 0.5 if kidney shaped or long slotted holes are used.
    . Shear capacity should be reduced for large packing, grip lengths or long joints.
