| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening nuts, which can deform the pipe or the U-bolt. | Tighten nuts to the manufacturer's recommended torque specification or until a snug fit is achieved, avoiding excessive force. |
| Using incompatible materials for nuts and washers, leading to galvanic corrosion. | Always use nuts and washers made from 316 stainless steel when used with a 316 stainless steel U-bolt to prevent dissimilar metal reactions. |
