Nickel is the most diverse metal and can be combined with other materials to form very powerful and high performance materials. Due to their great corrosion resistance, Nickel Alloy Fasteners of Unifit Fasteners are highly preferred in the context of where reliability is not a compromise. These are fasteners such as our own high quality nickel alloy bolts, which do astonishingly well in high temperature conditions where other steel alloy grades would oxidise or wear out.
In addition to their high resistance to oxidation, nickel alloy bolts have some resistance to reducing media and thus can be used in adverse industrial conditions. Commercially pure grades such as Nickel 200 Fasteners are generally employed at lower temperatures below 600 o C and they are highly resistant to caustic alkaline conditions. On the same note, UNS N02200 Hex Bolts provide good stability in dry fluorine, hydroxides and other harsh chemical environments.
Nickel 201 Fasteners contain less carbon than Nickel 200, making them less hard and less graphitization resistant in high temperatures. UNS N02201 Studs is an effective eliminator of intergranular embrittlement, and this is a frequent problem in traditional steels when they are subjected to temperatures exceeding 315 o C. This causes nickel alloy studs to be a reliable option where structural integrity over a long period is important.
In the case of Unifit Fasteners, you receive nickel alloy nuts, bolts, studs and threaded rods that remain strong, stable as well as corrosion proof even in the most hostile industrial settings.
Request QuoteThe Nickel 200 fasteners have found wide application in chemical manufacturing plants and food processing industries, as they have a very good resistance to corrosion. We produce different types of ASTM F2281 UNS N02200 Ni 200 fasteners at Unifit Fastener, such as hex bolts, socket cap screws, nickel 200 hex nuts, washers, threaded rods, studs, and U-bolts. These fasteners are of ASTM B160 standards, which are of the best quality and reliable.
Our 2.4066 nickel 200 stud bolts consist of a mixture of close to 99 per cent nickel metals, copper, iron, manganese, carbon, silicon and sulphur in specific proportions. In spite of the fact that ASTM F2281 nickel alloy bolts are likely to cost more, their high level of corrosion resistance makes them useful in sensitive industrial works where durability and performance are very important.
The Nickel 200 UNS N02200 hex nuts are particularly renowned because of their design, which is geometrical and capable of high torque. Unifit Fasteners, as a major producer and distributor, manufactures nickel alloy threaded rods, as well as a complete assortment of nickel 200 fasteners in different sizes and forms.

Unifit Fastener is a leading manufacturer of high-quality nickel alloy fasteners in India. Specializing in nickel 200 fasteners, bolts, nuts, and screws, Unifit Metalloys ensures compliance with international ASTM and ASME standards, delivering reliable solutions for demanding industrial applications.
A nickel screw is a fastening component made from pure nickel or nickel alloys known for corrosion resistance, high strength, and durability. Nickel screws are commonly used in harsh environments like chemical processing and marine industries.
Nickel bolts do not rust like iron; instead, they form a protective oxide layer that prevents rust. Though nickel can corrode in harsh acidic or humid conditions, its corrosion resistance is significantly higher than many other metals.
Nickel offers superior corrosion resistance and electrical conductivity compared to stainless steel, but stainless steel generally has higher strength and better abrasion resistance. Each has distinct advantages depending on the application.
Yes, screws can be made from pure nickel or nickel alloys for enhanced corrosion resistance and strength in industrial applications. Nickel plating on screws is also common to improve surface durability and appearance.
