Recommended max. tightening torque in Nm for untreated oil-smeared screws.
Friction coefficient µ=0.125, torque corresponds to approx. 62% of tensile bolt stress.
Friction coefficient µ=0.14, torque corresponds to approx. 90% of tensile bolt stress.

Every bolted joint is unique and the optimum tightening torque should be determined for each application by careful examination. A properly tightened bolt is one that is stretched such that it acts like a very ridged spring pulling mating surfaces together. The rotation of a bolt (torque) at some point causes it to stretch (tension).

Several factors affect how much tension occurs when a given amount of tightening torque is applied.

  • The first factor is the bolt's diameter.
  • The second factor is the bolts grade. It takes more force to stretch an SAE grade 8 bolt (or a 12.9 quality bolt) than it does to stretch an SAE grade 5 bolt (or a 8.8 quality bolt) because of the greater material strength.
  • The third factor indicates that harder, smoother and/or slicker bolting surfaces, such as threads and bearing surfaces, require less rotational force (torque) to stretch (tension) a bolt than do softer, rougher and stickier surfaces.
