| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the cap screw, which can strip threads or cause material fatigue. | Utilize a torque wrench to adhere to specified torque values for the fastener and mating material. |
| Using the wrong size or type of wrench, leading to cam-out and damage to the hex head. | Employ a properly sized six-point socket or wrench that fits snugly on the hex head. |
