| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the brass screw, which can lead to thread stripping or deformation. | Tighten to the recommended torque specification for brass fasteners, or use a torque wrench to avoid excessive force. |
| Using a steel tool on the brass head, potentially damaging the fastener or the tool. | Utilize brass or plated steel tools that are compatible with softer metals to preserve the integrity of the hex head. |
