Will this tool damage my bottom bracket?

Troubleshooting
Wrench slips during use
Ensure the double-threaded screw is fully and correctly threaded into the bottom bracket axle. Check that the 24mm screw head is properly engaged by your external wrench.
Difficulty removing or installing bottom bracket
Apply appropriate force using the 24mm wrench on the screw. For removal, ensure the crank arm is secured and not interfering. For installation, ensure threads are clean and lightly greased. Use a torque wrench for precise installation.
Screw does not thread easily
Clean the threads of both the wrench screw and the bottom bracket axle. Ensure you are using the correct side of the double-threaded screw for your specific bottom bracket type.
