Stainless Steel Fasteners
- Stainless steel fasteners offer natural corrosion resistance without requiring an additional coating, making them suitable for outdoor, marine and wash-down environments.
- The most common grades are austenitic stainless steels such as 304 (A2) and 316 (A4), selected by the level of corrosion exposure required.
Key properties
Typical reference values — confirm with a certificate.
| Common grades | 304 / A2-70, 316 / A4-80 |
|---|---|
| Magnetic | Generally non-magnetic (austenitic) |
| Corrosion resistance | Good to excellent; 316 better in chloride environments |
| Service temperature | Suitable for general ambient and moderate ranges |
| Typical surface | Natural bright metallic finish |

Important notes
- Do not confuse 'stainless' with 'corrosion-proof'; grade choice affects performance in harsh environments.
- Galvanic contact with more noble metals can still cause corrosion; confirm assembly compatibility.
- Mechanical properties depend on work hardening; verify class where high strength is needed.
