Eye nuts are another type of lifting eye. Eye nuts are subject to the DIN 582 standard. This means that the eye nut meet standard dimensions and quality. The design of the eye nut (sometimes also called the lifting nut) is similar to that of the eye screw except that the frame containing the eye nut does not contain the eye screw but is equipped with a bore with an internal thread instead. The internal thread of the eye nut has a standardized pitch. Eye nuts are available in metric dimensions M6 - M36. Eye nuts are applied at the end of a threaded rod or a steel screw.
