Alloy 400 · UNS N04400
A Monel 400 eye bolt is a bolt with a loop head for lifting or anchoring. Finished fastener specification not asserted; material/feedstock may be supplied to ASTM B164 (UNS N04400), where applicable; manufacturing route and finished fastener requirements are to the purchase specification or project drawing. Eye bolts provide lifting points on equipment. Load ratings depend on angle of pull.

Monel 400 Eye Bolt: Why 400 for eye bolts
Eye bolts provide lifting points on equipment. Load ratings depend on angle of pull. In Monel 400, the choice usually comes down to the medium and temperature — the rows here are the points buyers check for this exact combination.
| Why this grade | Nickel-alloy fasteners match nickel-alloy flanges in corrosive or hot service. Monel 400 is picked for seawater, hydrofluoric acid and marine service. |
|---|---|
| Typical service | Marine — Pump shafts, valves and seawater piping. |
| Bolting | B7 (coated), B8M or nickel-alloy studs in Monel 400 (bar to ASTM B164, where applicable), as the project specifies |
| Sour service | Listed in NACE MR0175 / ISO 15156-3 within its limits — state it on the order |
