| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening brass fasteners. | Brass is softer than steel; apply torque gradually and avoid excessive force to prevent thread stripping or fastener deformation. |
| Using incompatible tools. | Ensure the wrench or socket size precisely matches the 15mm head width to prevent cam-out and damage to the fastener head. |
