Inconel Hex Bolts

Inconel is an austenitic nickel-chromium-based superalloy that is commonly used in extreme environments. Due to the thick protective passivating oxide layer that forms when heated, Inconel fasteners can withstand immense degrees of pressure and heat that would destroy common material. The Inconel superalloy also retains its strength over a broad temperature range, making it highly useful for aerospace and automotive applications.

Fastener Solutions is an industry-leading provider of top-of-the-line Inconel hex bolts and screws. These hex bolts utilize the classic six-sided forged heads and can be used in conjunction with a nut or a tapped hole for quick and efficient turning and fastening. Whether you are looking for Inconel 600, 625, or 718 fastener bolts, Fastener Solutions has you covered.

Inconel 600 Hex Bolts

Inconel Hex Bolt

Hex bolts that are manufactured with Inconel 600 provide excellent mechanical properties, including high strength and good workability. Inconel 600’s high nickel content provides excellent corrosion resistance, which makes it highly resistant to chloride-ion stress-corrosion cracking. Inconel 600 hex bolts also provide proven resistance to high-temperature oxidizing conditions. Additionally, these super-strong hex bolts are cold work hardened and strengthened for extreme dependability.    

Applications of Inconel 600 Hex Bolts

Hex bolts that are manufactured with Inconel 600 are often utilized for applications that require extreme strength and corrosion resistance. These applications can include the following: Group of six Inconel hex fastener boltsGroup of six Inconel hex bolts

  • Heaters
  • Stills
  • Condensers
  • Tube sheets
  • Bubble towers
  • Flaking trays

Inconel 625 Hex Bolts

Inconel 625 superalloy combines molybdenum, niobium, nickel, and chromium to create a material that maintains excellent high strength, corrosion resistance, and fabricability.  The unique elemental combination of Inconel 625 hex bolts provides exceptional resistance to the most corrosive environments in the world. Inconel 625 hex bolts can also withstand extreme amounts of oxidation and carburization.

Applications of Inconel 625 Hex Bolts

Due to its many unique high-end properties, Inconel 625 hex bolts are used for applications that regularly encounter large amounts of stress within unpredictable environments. The industries that most often utilize Inconel 625 hex fastener bolts include:

  • Chemical processing
  • Aerospace
  • Marine
  • Nuclear

Inconel 718 Hex Bolts

Inconel Superalloy 718 is a precipitation hardenable nickel-based alloy that is designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300°F. Due to the heating and quenching process that is used to change its atomic structure, Inconel 718 hex screws are stronger than Inconel 625 bolts and gain additional strength through the cold working process.

Inconel 718 Hex Bolt Applications

Often utilized by high-end industries for their high-temperature strength capabilities, Inconel 718 hex bolts deliver strength and ductility at extremely hot and cryogenic temperatures. Inconel 718 hex fastener bolts are regularly used for the following types of applications:

  • Chemical processing
  • Nuclear reactors
  • Turbine engines
  • Oil shafts
  • Natural gas processing
  • Cryogenic tanks
