| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to head stripping. | Always use a wrench that precisely fits the 11mm hex head to ensure proper torque application and prevent damage. |
| Over-tightening, which can strip threads or damage components. | Adhere to the recommended torque values for M18 fasteners. Consult engineering specifications for your specific application. |
| Using incompatible materials that can lead to galvanic corrosion. | Ensure all mating components are also made of 316 stainless steel or are compatible with its electrochemical properties. |
