| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a non-matching wrench size, leading to cam-out and stripped heads. | Always use a properly sized hex wrench or socket for the M5 head to ensure effective torque transfer and prevent damage. |
| Over-tightening, which can strip threads or compromise the joint's integrity. | Adhere to recommended torque specifications for the application and material being joined to avoid overstressing the fastener or workpiece. |
