| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to head stripping. | Always use a wrench that properly fits the 22mm hex head to ensure optimal torque transfer and prevent damage. |
| Overtightening, which can lead to thread damage or fastener failure. | Adhere to the manufacturer's or engineering specifications for torque values. Excessive force can compromise the integrity of the joint. |
