Inconel 718 Screws (UNS N07718, WNR 2.4668)

Inconel 718 Screws are precision-engineered fasteners, including socket head cap screws and set screws, utilized in highly critical assemblies where reliability under extreme conditions is paramount. Fabricated from the age-hardenable Nickel Alloy 718 (UNS N07718), these fasteners exhibit superior mechanical properties, particularly remarkable yield and creep-rupture strength maintained up to $700∘C. The alloy's composition, rich in chromium and nickel, also provides exceptional corrosion resistance, guarding against oxidation and stress-corrosion cracking in harsh chemical environments. These Alloy 718 screws are indispensable in the aerospace industry for jet engine components, gas and steam turbines, and in high-performance racing components. Zeron Fastners ensures the supply of these high-strength screws, manufactured to tight dimensional tolerances for optimal fit and performance.
