| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the brass screw, which can lead to thread stripping or deformation. | Apply torque according to manufacturer specifications or engineering guidelines for brass fasteners. Use a torque wrench for precise control. |
| Using the wrong size or type of tooling, which can damage the hex head or lead to inefficient tightening. | Ensure the correct size of socket or wrench is used to match the 24mm hex head dimension for optimal engagement and torque transfer. |
