| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to thread damage or fastener failure. | Always adhere to the manufacturer's recommended torque specifications for the application and ensure the use of a calibrated torque wrench. |
| Using incompatible tools for tightening, potentially stripping the hex head. | Utilize a correctly sized 19mm socket or wrench that fits snugly to prevent cam-out and damage to the hex head. |
| Failing to adequately clean mating threads, hindering proper engagement and torque application. | Thoroughly inspect and clean both the screw threads and the internal threads of the mating component before installation. |
