| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening the aluminum screw, which can strip the threads or deform the mating surface. | Always use a torque wrench set to the manufacturer's recommended torque specification for Aluminum 6061 fasteners. |
| Using excessive force with an impact driver, which can lead to fastener failure or damage. | Impact drivers should be used cautiously or avoided altogether with aluminum fasteners. Hand-tightening followed by controlled torque application is preferred. |
