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.

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

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

breakaway force (lbf) = 300

screw lead (in) = 5

BT = BF * SL / (2*pi)** **= ?
