| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to thread stripping or material deformation. | Adhere to the recommended torque values for the specific application and materials being joined. Utilize a calibrated torque wrench for precision. |
| Using the wrong size hex wrench, resulting in damaged screw head or inefficient torque transfer. | Always use a hex wrench or socket that precisely fits the 24mm head width of the cap screw to ensure proper engagement and prevent cam-out. |
