China Aluminum Screws, Inc.’s Inconel 718 heavy hex bolts are high strength and corrosion resistant. They are the perfect bolt for anything from gas engine turbines to cryogenic tanks.

Inconel 718 heavy hex bolts are ideal for extreme environments that require oxidation and corrosion resistant bolts, even when subjected to pressure and heat. Inconel 718 heavy hex bolts are also twice as strong as Inconel 625 heavy hex bolts.

Additionally, due to their nickel-chromium content, Inconel 718 heavy hex bolts have excellent resistance even when combating chloride-ion stress-corrosion cracking. The addition of molybdenum to the alloy helps prevent pitting.
