| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong thread size or pitch. | Always verify the thread specification (M6 coarse in this case) matches the mating component's threads to prevent damage and ensure a secure connection. |
| Over-tightening the cap screw, leading to thread stripping or fastener failure. | Employ a calibrated torque wrench and adhere to recommended torque specifications for the material and application to prevent overstressing the fastener. |
