🔩 ACE Prop Wrench Calculator
How to Use This Tool
This calculator is only for ACE prop wrenches (other wrenches require different calculations).
👉 If your wrench is at a 90° angle (see Picture 1 below), use the manufacturer's torque setting — no change is needed!
If your ACE wrench is in-line — meaning it's EXTENDING the wrench (see Picture 2 below) use this tool to calculate the correct setting.
- Enter the torque you want to apply and select which unit (ft-lb or in-lb).
- Enter the length of your torque wrench, from center of handle to center of square drive, in inches. (see Picture 3 below)
- Press the "=" sign to calculate.
