Nickel alloy fasteners are widely used due to their strength and ductility. Nickel superalloys exhibit high strength coupled with high temperature resistance and are used for high stress, high heat applications. Wrought nickel alloys are characterized by their anti-corrosive properties as well as the high strength and temperature resistance properties found in the other nickel alloys. Monel, Haste
lloy and Inconel are widely used wrought alloys. While they do produce high strength fasteners, nickel alloy screws, bolts, nuts and studs are difficult to machine and require special handling to avoid work hardening and brittleness. Specifications
