What is the torque for 17mm bolt?

Metric Recommended Bolt Torque

What’s the difference between torque and breakaway torque?

Breakaway torque is defined as how much torque is required to start a part’s rotation from a stationary position. Running torque is the determination of how much torque is required to keep the part rotating at a constant angular velocity once it starts rotating.

Is breakaway torque the same as tightening torque?

Breakaway torque is the rotating force required to “break” the head loose, going in the same direction as applied – tightening. This will usually give a value HIGHER than the original tightening torque because dynamic (when the bolt was tightened) is lower than static (when you try to break loose the bolt head).

What are the recommended torques for an assembly?

What is the ISO standard for torque tools?

For the calibration of hand torque tools, an applicable standard is ISO 6789 Assembly tools for screws and nuts, Hand torque tools, Requirements and test methods for design conformance testing, quality conformance testing and recalibration procedure. This standard defines various types of torque tools.
