Our Inconel 625 hex nuts pair perfectly with our Inconel 625 bolts. Their corrosion resistance and high-temperature resistance with ultimate tensile strength make them the perfect fastener for any of your extreme applications.

KD Fasteners, Inc.’s Inconel 625 hex nuts offer excellent strength and toughness in the temperature range of cryogenic to 2000°F. Inconel 625 is a nickel-based alloy, but its high strength capabilities are due to the addition of molybdenum and niobium on its nickel-chromium matrix.

Inconel 625 is also, therefore, resistant to a wide range of corrosive environments of unusual severity. From remaining free from pitting and crevice corrosion in saltwater applications to withstanding a wide range of environments including sulfuric acid, hydrochloric acid, and phosphoric acid, Inconel 625 hex nuts are the nut of choice in extreme applications.
