Eyebolts are made from higher tensile steel, and if screwed into the same strength material, would need only to engage for a length equal to that of a full nut. However, it is possible and even likely that the material they are screwed into will be considerably weaker. The screwed length is therefore extended to compensate. DIN 580 and BS 4278 British standards for fixed rings are similar, mainly used for lifting and connecting applications. This is a German standard for fixed rings, commonly used in lifting, fixing, and connecting applications. It has certain load-bearing capacity and safety factors, and has passed a series of tests to ensure its quality and reliability. In addition, different countries and regions may have other standards and specifications for fixed rings. If you need to choose a fixed ring for a specific application, it is recommended to consult with professional engineers or suppliers to obtain more detailed and accurate information.
