| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, which can strip the aluminum threads or deform the mating surface. | Use a torque wrench set to the manufacturer's recommended torque specification for M4 aluminum fasteners. |
| Using the wrong tool, leading to cam-out and damage to the hex head. | Always use a properly sized hex bit or wrench that fits snugly into the screw head. |
