|---|---|---|
| SS 304 (General Purpose) | Inland, semi-urban, standard environments | Excellent corrosion resistance at lower cost than SS 316 |
| SS 316 (Marine Grade) | Coastal, offshore, high-salinity, chemical environments | Added molybdenum — superior resistance to chloride and sea air |
Supply Options
| Assembled Set | Bolt + Nut + 2x Plain Washer + Spring Washer, pre-assembled — best for site installation teams |
