| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force, which can strip threads or damage the brass material. | Apply torque gradually and use a torque wrench calibrated for brass fasteners if precise load is required. |
| Mating brass screws with incompatible materials (e.g., certain aluminum alloys) without proper precautions, leading to galvanic corrosion. | Consider using dielectric grease or isolating washers when joining brass with dissimilar metals prone to galvanic corrosion. |
