AISI 1045 fasteners are manufactured for applications requiring high strength and hardenability. AISI 1045 fasteners have additional advantage of being low cost over most high tensile bolting material. AISI equivalent CK45 are often most common starting material for mass production of high tensile fasteners including bolts, screws, stud bolts, threaded rods, nuts, etc. AISI 1045 is used in most industries including stuctural construction, maring and offshore, power planta and many other industrial projects.
