| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an incorrect size wrench, leading to stripped hex heads. | Always use a wrench that precisely matches the 15mm head width of the screw. |
| Over-tightening, which can damage the screw threads or the mating component. | Adhere to recommended torque specifications for the application to prevent fastener failure or damage. |
| Using the wrong thread size, resulting in a loose or non-functional joint. | Verify that the M8 thread size of the screw is compatible with the M8 threaded hole or nut. |
