Failure Threat Matrix[5,6,7]
| Failure Mode | Likelihood | Est. Onset | Mitigation Strategy |
|---|---|---|---|
| Fastener Rounding | Low | Random | Use ASD (Anti-Slip Design) end which engages flats rather than corners. |
| Chrome Peeling | Very Low | Random | Satin finish is less prone to peeling than chrome; keep dry to prevent underlying rust. |
