What this tool is used for
- Applying controlled leverage to approved fasteners during removal
- Reducing reliance on impact force
- Holding a compatible drive socket square to the fastener
A tool produces useful evidence only when its rating, setup, test conditions, and reference limits are correct.
- 01ChooseApplying controlled leverage to approved fasteners during removal
- 02Set upVerify the fastener direction and socket fit / Inspect the bar, drive, and socket rating
- 03MeasureSeat the socket fully / Position your body for controlled movement
- 04InterpretIt is not a torque wrench
- 05RecordPreserve setup, conditions, result, and next test
Follow the sequence, stop when evidence changes the path, and verify the exact vehicle information before acting.
Before you use it
Verify the fastener direction and socket fit
Inspect the bar, drive, and socket rating
Confirm the vehicle or component is supported against the applied force
A test-first working method
Seat the socket fully

Safety boundary
Leverage can move the vehicle
Use rated support on a stable surface and keep your body out of the fall path. A jack alone is not support.
