| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a standard wrench that does not fully engage the hex head, leading to cam-out and potential damage. | Utilize a correctly sized socket or box-end wrench that fits snugly around the hex head for maximum grip and torque transfer. |
| Cross-threading the screw by forcing it into the hole at an angle, which damages both the screw and the mating threads. | Start threading the screw by hand to ensure it is entering the hole straight and smoothly before applying any torque. |
