How to Use the Wrench Screw?

The Wrench Screw allows you to tighten or loosen it without a screwdriver.

You can rotate the handle clockwise to tighten the screw and rotate the handle counterclockwise to loosen it.

If you can't tighten or loosen the screw because the handle is blocked, you can do as follows.

1. Hold the handle to draw it away from the thread part.

2. Rotate the handle to stop it from being blocked.

The screw is not tightened or loosened when you rotate the handle.

3. Release the handle.

The handle goes back to the default position.

4. Rotate the handle to tighten or loosen the screw.
