Eye screws are the most frequently used type of lifting eyes. Eye screws are manufactured according to the DIN 580 standard which provides the standard parameters for ensuring the required properties of the eye screw. The design of the eye screw is generally very simple. A frame providing contact with the lifted load is welded onto a basic steel eye. The eye screw with its metric thread and standardized pitch protrudes from the frame. GUFERO eye screws are supplied in the sizes M6 - M48. This means that we are able to find the exact size you need for your application. The eye screw (sometimes called lifting screw) is applied to the pre-prepared internal thread in the lifted load, or alternatively to attach the eye screw into a bore and to secure it with a nut.
