| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to stripped head or compromised torque. | Always use a wrench or socket that precisely fits the 23mm hex head to ensure proper torque application and prevent damage. |
| Cross-threading the fastener, causing damage to both the screw and the mating component. | Carefully align the screw with the threaded hole and initiate tightening by hand to confirm proper thread engagement before applying power tools. |
