| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a non-stainless steel tool for tightening, which can lead to galvanic corrosion. | Always use tools made of compatible materials, such as stainless steel or high-quality plated steel, to avoid contaminating the fastener surface. |
| Over-tightening the screw, which can strip threads or cause material fatigue. | Refer to torque charts specific to M6 threads and the materials being joined, and use a calibrated torque wrench for precise application. |
