| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the cap screw, leading to thread stripping or component deformation. | Utilize a calibrated torque wrench and adhere to specified torque values for the fastener and application. |
| Using the wrong size wrench or socket, which can damage the hex head and lead to improper tightening. | Always use a wrench or socket that precisely matches the 24mm head width of the cap screw. |
