DIN 580 eye bolt working load

The permitted load depends on the steel grade, the angle of pull and the condition of the bolt and the thread it sits in. Always take it from the marking on the eye bolt and the supplier's instructions. The CAD file is for drawing and does not replace that check.

Eye bolt dimensions

The table gives the eye, the collar and the threaded shank. At M12 the eye is 30 mm inside and 54 mm outside, the bolt is 53 mm high above the collar face and the thread is 20.5 mm long. The tapped hole has to be deep enough for the full thread so the collar sits flat on the surface.
