How to use

Select the L‑key of the correct metric size from the holder and insert the short or long arm into the hex socket as required for clearance and leverage. Apply steady, controlled torque using the long arm for higher leverage or the short arm for confined spaces. After use, return keys to their designated slots in the holder to keep sizes organized and visible.
