Pressure and heat are nothing to worry about when using Inconel 718 socket cap screws. That’s why they’re the perfect fastener for aircraft and rocket components as well as power generation turbines and nuclear reactors.

Inconel 718 socket cap screws are ideal for extreme environments that require oxidation and corrosion resistant bolts, even when subjected to pressure and heat. Also known as alloy 718, Inconel 718 socket cap screws are also twice as strong as Inconel 625 socket cap screws.

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