| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to thread stripping or component damage. | Always use a calibrated torque wrench and adhere to specified torque values. |
| Using the wrong size wrench, which can lead to cam-out and damage to the hex head. | Ensure the wrench is the correct size (28mm in this case) and fits snugly on the hex head. |
| Installing without cleaning mating surfaces, compromising joint integrity and potentially causing galling. | Thoroughly clean all mating surfaces and threads before installation. |
