| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a socket that is too large or too small for the 28mm head width, leading to cam-out and potential damage to the fastener. | Always use a correctly sized socket for the 28mm hex head to ensure maximum engagement and prevent stripping. |
| Over-torquing the fastener, which can lead to thread stripping, bolt fracture, or distortion of the mating components. | Refer to torque specifications for the specific application and materials being joined, and utilize a calibrated torque wrench. |
