| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an improperly sized wrench, leading to head stripping or inadequate torque. | Always use a wrench or socket that precisely matches the 27mm head width for optimal force transfer and fastener integrity. |
| Over-tightening, which can lead to thread damage or deformation of the clamped material. | Apply torque according to engineering specifications for the specific application. Use a torque wrench for precise control if required. |
