Monel K500 Socket Head Cap Screws

Monel nickel copper K500 socket head cap screws are manufactured with a cylindrical head and provide the user with internal wrenching capabilities. This unique design allows the UNS N05500 socket head cap screws to be used in smaller, more confined spaces. The Monel K500 material is an age-hardenable Nickel-Copper alloy which combines the corrosion resistance of Alloy 400 with high strength corrosion fatigue and erosion resistance. In addition, the NiCu K500 socket head cap screws material also retains the excellent corrosion resistant characteristics of 400 and has enhanced strength and hardness after precipitation hardening when compared with 400.

At Fastener Solutions our Monel K500 socket head cap screws are available in numerous sizes and quantities. Contact us for more information regarding our line of Monel K500 socket head cap screws, or call us at 866-463-2910 with any questions. 


Monel 500 Socket Head Cap Screws

Monel K500 ASTM socket head cap screws are regularly used for a wide range of standard and advanced applications. Some of the specific applications include:

  • Propeller & pump shafts.
  • Surgical blades & scrapers
  • Transfer piping from oil refinery crude columns.
  • Cladding for the upper areas of oil refinery crude columns.
  • Feedwater and steam generator tubing.
  • Brine heaters, sea water scrubbers in tanker inert gas systems.
  • Sulfuric acid and hydrofluoric acid alkylation plants.
  • Electronic components.
  • Heat exchangers in a variety of industries.

Monel K500 Nickel Copper Alloy Chemical Composition

Monel K500 ASTM has a chemical composition of roughly 65% nickel, 30% copper and 3% aluminum. Monel K500 exhibits extremely good corrosion resistance with added high strength corrosion fatigue and erosion resistance. Some of the additional material advantages that Monel K500 fasteners display, include:

  • Melting range between 2400-2460° F.
  • 92,500 psi min. tensile strength
  • Cold worked strengthened
  • Chloride ion stress corrosion cracking
  • Excellent corrosion resistance

Monel 400 vs Monel 500 Socket Head Cap Screws

Essentially, Monel K500 is an age-hardened version of Monel 400. This means that Monel K500 is harder and more corrosion resistant than Monel 400. Monel K500 is ideal for marine applications, where the cap screws will be integrated with salt water on a consistent basis. On the other hand, Monel 400 has high strength and toughness over a wide temperature range and is resistant to many corrosive environments but is not used in as highly of corrosive environments as Monel K500. However, Monel 400 is still ultra-strong and one of the best specialty nickel copper alloys in existence.


Monel K500 manufactured socket head cap screws are ideal for tight fitting applications that require the use of a socket wrench for proper screw adjustments. Additionally, Monel’s natural anti-corrosive proprietary qualities allow it to be used where other fastener materials would fail, which allows this alloy to be used for fasteners of all types. Some of the benefits specifically related to cap screws versus regular fasteners, include:

  • Less socket screws are required to achieve a specific clamping force, when compared to ordinary fasteners.
  • Since not as many socket screws are required, not as many holes need to be drilled and eventually tapped.
  • Fewer screws mean less overall weight.
