| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, which can lead to thread stripping or material fatigue. | Always use a calibrated torque wrench and adhere to the recommended torque specifications for Titanium Grade 5 fasteners. |
| Using incompatible tools or forcing the screw, potentially damaging the head or threads. | Employ the correct size and type of wrench for the hexagonal head and ensure smooth engagement of the threads. |
| Not cleaning mating surfaces, which can introduce debris and compromise the joint integrity. | Thoroughly clean both the screw threads and the receiving threads or hole before installation. |
