prob_01
Common root cause: Using the wrong tool or overtightening, damaging the screw threads.
Step-by-step solution: Check the package for a spare screw. If none is included, purchase a replacement nickel-plated brass screw with the same specifications (M4 or M5, depending on the model) from an electrical supply store. Carefully replace the damaged screw, using the correct tool and applying moderate torque.
💡 Pro tip: Always use a screwdriver (Phillips or flathead) that matches the screw's size and type. Tighten gradually until firm resistance is felt, without forcing it.
