Does ISO 898-1 specify bolt shear strength?

No. Its official scope explicitly excludes requirements for shear resistance. This page therefore generates no shear capacity.

Are the displayed loads design resistances?

No. They are products of user-entered stress and tensile stress area, without joint geometry, partial factors, fatigue, bearing, slip, tear-out, interaction or connection-code checks.

Where should the inputs come from?

Use the current applicable fastener/thread standard, verified manufacturer data or a material certificate for the exact diameter, pitch, property class, temperature and product geometry.

Scoped Engineering Calculation

Bolt Axial Stress-Area Loads

Calculate F=σ·As for user-supplied ultimate and reference axial stresses. No shear capacity or design resistance is inferred.

MPa is N/mm², so each product is in newtons. “Ultimate product” is not a guaranteed specimen result or design resistance; the entered Rm and As must match the exact fastener and applicable source.

ISO 898-1 scope

ISO 898-1:2013, confirmed in 2025 and marked for revision, covers specified mechanical/physical properties for carbon/alloy-steel metric fasteners M1.6–M39 at 10–35 °C. It explicitly excludes requirements for shear resistance, fatigue and torque/clamp performance. The previous M3–M64 property-class lookup and “0.6 shear capacity” have therefore been removed.

Why double shear is not just a selector

Connection resistance depends on whether each plane crosses threads or shank, actual shear area, material model, bearing and tear-out of connected parts, slip, eccentricity, load sharing, combined tension/shear, fatigue and the governing code. A generic 0.6RmAs multiplied by plane count cannot establish capacity.

Inputs: obtain As, Rm and the chosen reference stress from the current licensed standard, verified manufacturer data or material certificate for the exact diameter, pitch, property class, product geometry and temperature.
