| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect tool size, leading to stripped head. | Always use a correctly sized metric socket or wrench (e.g., 11mm) for M7 hex heads to ensure proper engagement and prevent damage. |
| Over-tightening, causing thread damage or material fatigue. | Consult torque specifications for the application and use a torque wrench to apply the recommended torque. Avoid excessive force. |
| Using the wrong material for the environment, leading to corrosion. | Confirm that 304 stainless steel is suitable for the specific environmental conditions (e.g., exposure to salts, acids) and consider higher grades if necessary. |
