| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a wrench that is too small for the hex head, leading to slippage and potential damage to the screw head. | Always use a wrench that precisely fits the 29mm hex head to ensure proper grip and prevent stripping. |
| Over-tightening the brass screw, which can lead to deformation of the threads or the screw head. | Adhere to the recommended torque specifications for M12 brass screws to ensure a secure joint without compromising the fastener's integrity. |
