| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening, leading to thread stripping or fastener fracture. | Utilize a calibrated torque wrench and adhere strictly to recommended torque specifications for the fastener and application. |
| Using the wrong tool size, resulting in damaged hex head and improper torque application. | Always use a correctly sized, high-quality hex socket or wrench that fits snugly to the screw head. |
| Failing to inspect threads for damage or contamination before installation. | Visually inspect both the screw threads and the internal threads of the mating component for any signs of damage, dirt, or foreign material. |
