| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an improperly sized wrench or socket, leading to cam-out and damaged fastener heads. | Always use the correct size wrench or socket that fits snugly on the hex head to ensure proper grip and prevent damage. |
| Over-tightening the cap screw, which can strip threads or deform the mating components. | Adhere to the recommended torque specifications for the specific application and materials being joined. Use a calibrated torque wrench for accuracy. |
| Using a fastener that is not rated for the environmental conditions, leading to premature corrosion. | Ensure the 304 stainless steel designation is suitable for the intended environment. For highly corrosive conditions, consider higher-grade stainless steels or specialized coatings. |
