Unifit Fasteners is a manufacturer and supplier of quality grade Nickel 200 / 201 Hex Nuts that are of superior quality in terms of strength and hardness particularly when cold worked. Nickel UNS N02200 Hex Nuts are considered to have excellent performance among formable cobalt alloy and can be used in continuous service up to 1800 o F. These alloys are among the most documented materials owing to their long history of use and reliability in different conditions and therefore they are studied widely to understand their behaviour under different conditions. However, like many high-performance alloys, prolonged exposure to mid-range temperatures can lead to reduced ductility at room temperature.
Nickel 200 Hex Nuts are fastening components made from pure wrought nickel (UNS N02200) known for its exceptional resistance to corrosive environments, high thermal stability & good mechanical properties. These nuts are designed with a six-sided hexagonal shape which allows for easy tightening using standard wrenches or spanners to be used for secure & durable assemblies. It offers excellent resistance to alkalis, acids & salt solutions. It is non-magnetic making it suitable for sensitive applications where magnetic interference must be minimized.
Nickel 200 / 201 Hex Nuts will weld with GTAW, GMAW, SMAW, electron beam and resistance welding but not submerged arc welding. When proper joint fit-up is done, low interpass temperature and fast cooling take place, and the best results are guaranteed. To achieve maximum ductility, annealing of components at temperatures between 2150 and 2250°F with a fast cooling method must be used. The alloy has high resistance against both high-temperature oxidation and carburisation and works in environments that have hydrochloric acid, nitric acid, and wet chlorine.
Machining is typically smooth with no preference on stop milling, drilling and tapping. This material is best used with sulphur-chlorinated water-based cutting fluids. The alloy has a small increase in hardness and strength during aging of cold-worked parts, which makes them applicable in the area of high-temperature working, bearings and components with high galling resistance.
Nickel 200 Hex Nuts, made from pure nickel alloy (UNS N02200), offer excellent corrosion resistance, high thermal and electrical conductivity, and reliable mechanical strength. Selection depends on operating conditions like temperature, vibration, corrosive exposure, and installation requirements. They come in various types including heavyt hex nuts, hex jam nuts, hex lock nuts & hex wing nuts to suit different industrial needs.
At Unifit Fasteners, top nickel 200 hex nuts manufacturer & supplier, combine cutting-edge technology, rigorous quality control & customer centric solutions to deliver unmatched value in every product we manufacture.

Nickel 200 Hex Nuts are designed with tight tolerances to ensure a secure & consistent fit during assembly. Tolerance refers to the acceptable variation in the nut dimensions such as width across flats, thread diameter, & thickness which ensures compatibility with bolts & other fastening components. It will help to maintain accurate thread engagement, prevent loosening due to vibration to ensure a tight & leak-proof connection & allow for easy interchangeability between parts. To maintain these performance standards, Nickel 200 hex nuts are manufactured in accordance with international tolerance norms ISO 47591 for metric sizes & ANSI/ASME B18.2.2 for imperial sizes.
Both standards define the permissible dimensional variation in features like:
For example:
A 1/2" Nickel 200 hex nut may have a width across flats tolerance of ±0.01 inch depending on its grade and class. For metric M12 nuts, the tolerance class may be specified as "6H" indicating medium fit commonly used for general-purpose mechanical applications.
The thickness of Nickel 200 Hex Nuts varies based on the nut size & the applicable standards, such as DIN (German) or ANSI/ASME (American) specifications. Thickness is a critical dimension that influences the mechanical strength of the nut, its load-bearing capacity & the amount of thread engagement during assembly. Nickel 200 hex nut thicknes is essential for ensuring reliable performance in these critical applications. These dimensions conform to international norms & are suitable for industrial applications.
Below is a reference chart that outlines the standard thickness ranges for commonly used metric sizes of Nickel 200 hex nuts:
| Nut Size (Metric) | Thickness (mm) |
|---|---|
| M6 | 5.0 – 5.5 |
| M8 | 6.5 – 7.0 |
| M10 | 8.0 – 8.4 |
| M12 | 10.0 – 10.8 |
| M16 | 13.0 – 14.8 |

Nickel 200 is mainly used in chemical processing equipment, electrical and electronic components, and food handling systems. It performs well in caustic environments and areas requiring high corrosion resistance. Its purity and good mechanical properties make it suitable for heat exchangers, fasteners, and welded structures.
Nickel 200 contains slightly more carbon, giving it better strength at normal temperatures. Nickel 201 has lower carbon, which prevents embrittlement and makes it more stable for high-temperature applications. In simple terms, Nickel 200 is stronger at room temperature, while Nickel 201 is better suited for elevated heat conditions.
