Nickel Alloy 2.4068 Fasteners are available in various types to meet project requirements. A Nickel 201 bolt deliver high strength for mechanical assemblies and nickel 201 nut provide firm and reliable support for joining applications. Stud bolts and hex bolts are preferred in heavy-duty connections, while eye bolts handle lifting tasks with ease. Screws, washers, U bolts, and threaded bolts provide versatility for both common and specialist applications. Each type is engineered to withstand tension and resist wear, making them suitable for industries that require durability and accuracy.

ASTM B160 Alloy 201 Fasteners conform to dimensional standards such as ASTM, ASME, and API. We provide in sizes ranging from M3 to M56 and 3/6″ to 2″, with custom options available. Lengths extend from 3 mm up to 200 mm. Surface coatings include black oxide, cadmium, galvanized, Teflon, Xylan, zinc, and more upon request. UNS N02201 Fasteners are widely used in chemical plants, food processing units, marine equipment, and power generation systems because of their high strength and resistance to extreme conditions.
