| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a wrench that does not fully engage the hex head, leading to stripping. | Always use a properly sized socket or wrench that fits snugly onto the hex head for maximum contact and torque transfer. |
| Over-tightening the screw, which can damage the threads or the component being fastened. | Adhere to the manufacturer's recommended torque specifications for the specific application and material to prevent over-stressing the fastener. |
