DIN 80704:1968 Metric Bow Eye Nut uses a bow-shaped eye for metric threaded applications requiring connection to lifting gear, cables, or pulling elements. When threaded onto a mating externally threaded fastener, it creates a convenient attachment point for hanging or force transfer.

The product is commonly used in machinery, marine accessories, engineering installation, rigging connections, and light-to-medium lifting or pulling operations. The bow profile provides generous contact space for attachment hardware, making it suitable for joints that are frequently connected, removed, or directionally adjusted.

Selection should consider load rating, force direction, thread size, and service environment. Corrosion-resistant materials or surface treatments may be specified where needed to maintain safety margin and connection reliability over time.
