| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening brass fasteners, which can strip threads or deform the material. | Apply torque gradually and avoid excessive force. Refer to torque specifications if available for the application. |
| Using steel tools on brass, which can cause galling or damage the fastener head. | Use tools made from softer metals or ensure good lubrication to prevent galling. |
