Monel Fasteners has an alloy consisting traces of nickel (65-70%), copper (20-29%), and also it is comprised of iron, manganese, and other compounds. The commercially available forms of these fasteners are Monel 400 and Monel 500. Monel Fastneers are extremely resistant to corrosion under any atmospheric conditions. In pure oxygen these fasteners are fireproof. These fasteners due to light weight are widely preferred for connecting and tightening the stack of parts together.
Monel due to its superior anti-corrosion resistant properties is a good materials to be used as fastener in marine applications such as seawater valves, piping systems, trolling wire, strainer baskets, and pump shafts. These Monel fasteners are non-magnetic in nature, so they are used in directional drilling.
