| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size hex wrench, leading to stripped head damage. | Always confirm the correct wrench size (18mm) for the M19 hex head to prevent damage. |
| Over-tightening the screw, which can lead to thread stripping or material fatigue. | Adhere to the recommended torque specifications for the application to ensure secure fastening without damage. |
| Using a non-stainless steel fastener in a corrosive environment, resulting in premature failure. | Ensure 304 stainless steel fasteners are used in environments prone to moisture, salt, or chemical exposure. |
