| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to thread stripping or material fatigue. | Always use a torque wrench and adhere to specified torque values to prevent over-stressing the fastener and mating components. |
| Using incompatible lubricants or thread lockers that may react with titanium. | Consult material compatibility charts and use only lubricants or thread lockers specifically recommended for titanium fasteners to avoid galling or embrittlement. |
