Frequently referred to as a superalloy or a high performing alloy, the Nickel Alloy 718 Cap Screws are a Gamma Double Prime or symbolically as γ". Nickel based superalloy is a phase which conventionally either contains elements Niobium or Vanadium. In the case of Inconel Alloy 718 Bolt and Nut, the matrix of the alloy is stiffened with the addition of  Niobium along with molybdenum. The addition of niobium in the alloy is not only used to strengthen Nickel centric superalloys at lower temperatures but they are meant to strengthen Inconel 718, without the alloy undergoing a strengthening process. The crystal structure of this gamma Double Prime is accountable for the primary strengthening mechanisms of the Inconel 718 Screws.

As associated with standard behaviour of superalloys, the Inconel 718 is able to perform at a high fraction to that of its melting point. This being said, the Inconel 718 Hex Bolts is consistent with exhibiting behaviour typical of high performing alloys including excellent mechanical strength. Moreover, the Inconel 718 Washers not only evenly distributes the stress over the surface of the nut but also has the ability to make provisions for good surface stability in addition to having resistance to thermal creep deformation. A high point of the  Inconel 718 Fasteners is its rather excellent resistance to corrosion or oxidation. In fact, this resistance property of the Alloy 718 Hex Bolt is attributed to the addition of chromium to the alloy.
