| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening the cap screw, leading to thread stripping or component damage. | Always use a calibrated torque wrench and adhere to the recommended torque specifications for the specific application and materials being joined. |
| Using the wrong size or type of wrench, which can round the hex head and impede proper tightening. | Utilize a correctly sized socket or wrench that fits snugly onto the hex head to ensure full engagement and prevent slippage. |
