Use this engineering calculation for a transparent preliminary estimate or independent arithmetic check when geometry, materials, loads, operating conditions, and units are defined consistently.

Total Shear Newtons (N)

Required number input.

Bolt Count

Required integer input.

Average direct shear force per bolt for a concentric load shared equally by identical bolts; excludes eccentricity and prying. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Shear Per Bolt Newtons (N)

The resulting shear per bolt newtons returned as a number.

• Connection capacity depends on material grades, geometry, edge distance, pretension, threads, weld quality, prying, combined actions, fatigue, corrosion, and code resistance factors. A single tensile, shear, or stress check is not a complete connection design.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check assumptions against drawings, measurements, current material data, and the applicable design code. Apply required load combinations and safety factors, then obtain qualified review and testing for consequential designs.

• Anchor Bolt Tensile

  Average direct tensile load per anchor under equal concentric load sharing; not an anchor design-strength calculation.

• Bolt Tensile Capacity

  Nominal axial force from bolt tensile stress area times a user-supplied allowable tensile stress; excludes prying and interaction.

• Bolt Shear Capacity

  Nominal single-shear force from bolt shear area times a user-supplied allowable shear stress; not a code-rated connection capacity.
