| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the brass screw, which can strip the threads or deform the mating material. | Adhere to recommended torque values for brass fasteners, especially in softer materials. Use a torque wrench for precise control. |
| Using a steel wrench on a brass screw, which can damage the hex head profile and make future removal difficult. | Utilize brass or high-quality alloy steel wrenches specifically designed for hex heads to prevent marring. |
