1 to 100 Nm in 1 Nm steps, then every 5 Nm to 300. Values rounded to 2 decimal places (in-lb to 1). Need an exact figure? Use the converter. Going the other way? See the ft-lb to Nm chart.

Metric bolt torque chart

Typical tightening torque for dry, coarse-thread metric steel bolts into steel. Each cell shows Nm on top and ft-lb underneath. Columns are the bolt grade stamped on the head (8.8, 10.9 or 12.9).

Read before you tighten

Not for aluminium threads. Bolts into aluminium, magnesium or plastic (engine cases, calipers, bike frames) need much less. Use the maker's figure.
Oiled, greased, waxed or anti-seize threads: use roughly 20 to 25% less than these figures.
Zinc-plated bolts (the usual bright or yellow finish) are close to these dry figures.
Stretch bolts (torque-to-yield, such as cylinder head bolts) need torque plus an angle and are single use. Never use this chart for them.
Torque wrenches are least accurate below about 20% of their range. Wind a click wrench back to its lowest setting after use.

How these are worked out: 75% of the ISO 898-1 proof load, with a nut factor of 0.2 (dry, plain or zinc-plated steel into a steel nut). For guidance only. Where the manufacturer gives a torque figure, use theirs.
