| Requirement | Recommendation |
|---|---|
| Outdoor / marine / humid environments | A2 (SUS304) passivated — excellent general corrosion resistance |
| Flush or low-profile assembly | Pan head profile — wide bearing surface, minimal protrusion |
| High-torque or cam-out resistant drive | Pozidriv (Pozi) drive — superior to Phillips under high torque |
| Electronics / precision instruments | M1.6 – M3, short lengths; non-magnetic A2 grade |
| Structural / load-bearing assemblies | M5 – M10, A2-70 property class |
| Food processing / medical equipment | A2 SUS304 — hygienic, non-reactive surface |
| Compatibility with Phillips screwdriver | Pozi is backward-compatible with Phillips in most cases (Z1/Z2) |
