| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a wrench that does not fit the hex head snugly, leading to cam-out and potential damage to the fastener or tool. | Ensure the wrench or socket is the correct size and fits the hex head of the cap screw with minimal play. |
| Applying excessive torque, which can strip the threads or deform the fastener, compromising its structural integrity. | Always consult torque specifications for the application and material being joined, and use a calibrated torque wrench. |
