| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to thread stripping or material fatigue. | Always adhere to the manufacturer's specified torque values for the M19 size and material. Use a calibrated torque wrench. |
| Using an incorrect tool size for the 35mm head width, potentially damaging the screw head or the tool. | Utilize a properly sized socket or wrench (e.g., 35mm or equivalent fractional size) to ensure a secure grip and prevent cam-out. |
