| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an improperly sized wrench, leading to head stripping. | Utilize a wrench that precisely fits the 28mm hex head to ensure proper torque application and prevent damage. |
| Over-tightening, which can lead to thread stripping or fastener failure. | Adhere to the recommended torque specifications for the M23 diameter and the specific application to avoid overstressing the fastener. |
| Failing to clean mating threads, causing friction and inaccurate torque readings. | Thoroughly clean both the cap screw and the tapped hole or nut threads before installation to ensure smooth engagement and accurate tightening. |
