| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to head stripping. | Always use a wrench or socket that precisely fits the hex head (26mm) to ensure proper torque transfer and prevent damage. |
| Over-tightening, which can damage the threads or compromise the joint's integrity. | Adhere to recommended torque values for the specific application and materials being joined to avoid overstressing the fastener. |
