| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the fastener, leading to thread stripping or material deformation. | Utilize a calibrated torque wrench set to the recommended torque specification for the fastener and materials being joined. |
| Using the wrong size or type of socket, which can round the hex head, making removal difficult. | Always employ a correctly sized, high-quality socket that fully engages the hex head of the cap screw. |
