Inconel 600 Machine Screw: Why 600 for machine screws
Machine screws assemble instruments, panels and equipment. Pan, countersunk and cheese heads. In Inconel 600, 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. Inconel 600 is picked for high-temperature oxidation, caustic and nuclear service. |
|---|---|
| Typical service | Furnaces & heat treating — Muffles, retorts and radiant tubes. |
| Bolting | B7 (coated), B8M or nickel-alloy studs in Inconel 600 (bar to ASTM B166, where applicable), as the project specifies |
