Nickel Alloys Incoloy 800 Screws

Nickel Alloys Incoloy 800 Screws are externally threaded mechanical fasteners designed for secure assembly, often directly driven into a pre-tapped component. Manufactured from Incoloy 800 (UNS N08800), an alloy known for its high-temperature strength and stability, these screws are vital in applications where resistance to thermal stress, oxidation, and carburization is critical. The high nickel and chromium content provides exceptional defense against high-temperature corrosion and stress-corrosion cracking. Zeron Fastners supplies these reliable screws in various types (e.g., cap screws, machine screws, set screws) for use in heat treatment equipment, industrial furnaces, and petrochemical processing units.
