Non-Standards Are Our Standard

Inconel Bolts and Fasteners Manufacturer

Here at Smith Bullough, we offer Inconel bolts and fasteners with short production lead times.

What is Inconel?

Inconel is a nickel-chromium alloy, characterised by high tensile strength and outstanding corrosion resistance under a range of temperatures and pressures.

Properties of Inconel

Inconel is available in several grades. At Smith Bullough, we use Inconel 600, 601, 625 and 718 in the manufacture of our bolts and fasteners.

Inconel 600

Inconel 600 is a nickel-chromium alloy and is extremely resistant to corrosive environments.

Inconel 601

With the addition of aluminium, Inconel 601 provides increased performance at elevated temperatures.

Inconel 625

Inconel 625 contains molybdenum and is resistant to a wide range of severely corrosive environments.

Inconel 718

Inconel 718 is a precipitation-hardened nickel-chromium alloy, featuring excellent corrosion-resistance alongside high strength at elevated temperatures.

Types of Inconel Bolts & Fasteners

Smith Bullough manufactures a wide variety of Inconel fasteners and bolts on site. Whatever your particular requirements, we will have the appropriate solution. These include:

  • Hexagon bolts and set screws
  • Stud bolts
  • Engineer studs
  • Socket cap screws
  • Socket set screws
  • Socket countersunk screws
  • Nuts
  • Washers
  • Machined parts
  • Specials to drawing


High tensile strength, resistance to pitting and crevice corrosion as well as high corrosion fatigue strength are properties that make Inconel ideal for usage in seawater applications.

Outstanding corrosion resistance under a range of temperatures and pressures is a key reason why Inconel is also widely used in the aerospace, nuclear and chemical processing industries.
