What is Max locking torque?
So, the maximum locking (prevailing) torque going into the bolt is measured, as is the minimum torque required to remove the bolt. Semantically speaking, the torque value table measures the maximum torque for installation, and the minimum torque for removal.
How do you calculate torque needed to tighten a bolt?
The widely recognized engineering formula, T= K x D x P (to be explained later in this article), was used to provide the chart’s values, but it must be understood that every bolted joint is unique and the optimum tightening torque should be determined for each application by careful experimentation.
How is bolt torque calculated?
The basic formula T = K x D x P stated earlier takes these factors into account and provides users with a starting point for establishing an initial target tightening torque.
