| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the brass screw, which can lead to thread stripping or deformation. | Adhere to manufacturer-specified torque values and utilize a torque wrench for precise application. |
| Using steel tools on brass fasteners, which can cause galling or damage to the screw head. | Employ brass or aluminum tools, or tools with appropriate coatings, to minimize the risk of damage. |
