Nickel 200 (2.4060) fasteners are made from commercially pure nickel and are best known for their excellent performance in caustic alkali solutions such as caustic soda (NaOH). Nickel 200 also exhibits good performance in acids, especially HF (Hydrofluoric Acid - anhydrous) and hydroxides – but can be attacked by common solutions of hydrochloric or sulfuric acids.

From a mechanical perspective, Nickel 200 bolts have good ductility and low hardness, so they are tough, but not particularly strong (60-85 KSI UTS). See Tensile, Yield & Elongation Chart.

Corrosion
Nickel 200 screws are resistant to corrosive environments, most notably reducing chemicals. They offer outstanding protection to caustic alkaline solutions. However, Nickel 200 fasteners will be severely attacked in oxidizing salt solutions.
 
Chemical Resistance
•  Sodium Hydroxide (NaOH): Excellent resistance to all concentrations of caustic soda.
•  Alkalis: Excellent resistance except for ammonium hydroxide.
•  Sulfuric acid: Moderate resistance to nonaerated sulfuric acid solutions near room temperature.
•  Hydrochloric: Limited resistance in specific environments only.
•  Hydrofluoric: Good resistance to anhydrous hydrofluoric acid even at high temperatures. Nickel 200 it has limited resistance to aqueous HF solutions.
•  Important: Oxidizing acid chlorides such as ferric, cupric and mercuric are very corrosive to Nickel 200 fasteners.

General
•  60-85 KSI UTS
•  15-45 KSI Yield
•  Typically used in application temperatures less than 600⁰F / 315⁰C

Applications
•  Most often used in chemical and electronic processing, especially applications that deal with caustic soda.
•  High electrical and thermal conductivity, as well as magnetostrictive properties make Nickel 200 screws useful in electrics and sonic devices.
•  Nickel 200 bolts are used in salt production and applications that use sodium hydroxide and fluorine.

Nickel 200 Temperature vs. Strength

Nickel 200 Screws  

12 Point Screws	Nickel 12 point screws are an ideal choice when higher torque  than a socket head cap screw is needed. The only drawback is they are be less economical due to the complex head design. Available in 1/4" or larger sizes.	•  IFI-115 •  MIL SPEC •  DIN 34822 •  DIN 34821
Button Head Cap Screws	Offering a wide clamping area and low profile, Nickel 200 button head screws are best suited for fastening a material that is too thin to counter bore.	• ASME B18.3 • ASME 18.3.4M • DIN 7380 / ISO 7380
Flat Head Screws	Most commonly offered in an 82° countersink angle, Nickel 200 flat head screws but can be customized to other angles from 60° -120°. These screws are designed to be flush with the surface.  Nickel 200 flat heads are available in slotted and socket drivers. Phillips, torx and other tamperproof drivers can also be made upon request.	•  ASME B18.3 •  ASME B18.3.6 •  DIN 963 / ISO 2009 •  DIN 965 / ISO 7046 •  DIN 7991 / ISO 10642
Hex Head Cap Screws	Nickel 200 hex head cap screws feature an added washer face to the bolt head (lacking on a hex bolt) which provides tighter dimensional tolerances. Ideal for a high clamping force applications with ease of access. Generally availabe in #2 - 1/2" sizes and metric sizes.	• ASME B18.6.3 • DIN 931 / ISO 4014 • DIN 933 / ISO 4017 • DIN 961 / ISO 8676
Pan Head Screws	Nickel 200 pan head screws have a rounded head style and typically featured a slotted driver. They are best for small diameter fasteners and low torque applications.	• ASME B18.6.3 • DIN 7985 • DIN 921 • DIN 85 / ISO 1580 • DIN 84 / ISO 1207   (cheese head) • DIN 966 / ISO 7047   (raised counter sunk)
Security Screws	Nickel 200 security screws provide a solution to unwanted tampering or removal due to the fact that they cannot be removed using an ordinary driver. Nickel 200 security screws can be made in a wide variety of driver styles, as well as custom per print.
Set Screws	Nickel 200 set screws are a headless fastener with a slotted or socket driver on one end and a special point on the other. We offer Nickel 200 set screws in cup, cone, flat, dog and half-dog points.	• ASME B18.3 • DIN 913 / ISO 4026 • DIN 914 / ISO 4027 • DIN 915 / ISO 4028 • DIN 916 / ISO 4029
