Enter the breakaway force (lbf) and the screw lead (in) into the Breakaway Torque Calculator. The calculator will evaluate the Breakaway Torque.

## Breakaway Torque Formula

The following two example problems outline the steps and information needed to calculate the Breakaway Torque.

BT = BF * SL / (2*pi)

Variables:

• BT is the Breakaway Torque (lbf-in)
• BT is the breakaway force (lbf)
• SL is the screw lead (in)

To calculate a breakaway torque, multiply the breakaway force by the screw lead, then divide by 2 times pi.

## How to Calculate Breakaway Torque?

The following steps outline how to calculate the Breakaway Torque.

1. First, determine the breakaway force (lbf).
2. Next, determine the screw lead (in).
3. Next, gather the formula from above = BT = BF * SL / (2*pi).
4. Finally, calculate the Breakaway Torque.
5. After inserting the variables and calculating the result, check your answer with the calculator above.
