Why C1045 carbon steel Style D eye nuts?

C1045 is a medium carbon steel with more carbon than C1030, giving greater strength and hardness when heat treated, and the Style D pattern's larger section makes it the heaviest-duty carbon-steel eye nut choice for rugged, hard-service lifting. It threads onto a stud or bolt for straight, in-line loads. Seat the eye nut squarely on a flat surface or hardened washer, engage full threads (at least one bolt diameter in steel), and align the eye with the pull. Carbon steel is best protected from corrosion; choose galvanized or stainless where rust is a concern. Avoid side loading unless derated, and confirm the rated capacity before each lift.
