Product Overview This product line consists of drop-forged steel lifting eye bolts (DIN 580) and lifting eye nuts (DIN 582) with zinc-plated (galvanized) finish, designed for safe and reliable lifting, hoisting, and load-suspension applications. The eye bolts and eye nuts are manufactured from C15E case-hardening steel (1.1141 / 1015) in accordance with German standard DIN 580 and DIN 582, and are available in thread sizes from M6 to M64 (eye bolts) and M6 to M64 (eye nuts). The zinc-plated finish provides reliable corrosion protection for general industrial, construction, and outdoor applications. The forged construction ensures high load-bearing capacity with a minimum safety factor of 6:1 (working load limit is one-sixth of the minimum breaking load), making these products suitable for lifting and transport tasks in machinery, construction, logistics, and material handling.

Material & Construction Parameter DIN 580 Eye Bolt DIN 582 Eye Nut Material C15E case-hardening steel (1.1141 / 1015) C15E case-hardening steel (1.1141 / 1015) Manufacturing Drop-forged, annealed, contact face machined Drop-forged, annealed, contact face machined Surface Finish Zinc plated, blue passivated (A2K) Zinc plated, blue passivated (A2K) Temperature Range −20°C to +200°C (without load reduction) −20°C to +200°C (without load reduction) Safety Factor 6:1 minimum 6:1 minimum Marking CE mark, WLL, manufacturer ID, thread size, batch number CE mark, WLL, manufacturer ID, thread size, batch number C15E steel is a case-hardening carbon steel specifically selected for lifting applications due to its excellent combination of strength, toughness, and ductility. The drop-forging process ensures a continuous grain flow that follows the contour of the eye, optimizing load distribution and fatigue resistance. DIN 580 eye bolts are suitable for use at temperatures ranging from −20°C to +200°C without a reduction in lifting capacity. Zinc plating provides sacrificial (cathodic) protection to the underlying steel. The zinc coating corrodes preferentially, protecting the steel substrate from rust. The standard blue-passivated (A2K) finish offers good corrosion protection for indoor and general industrial applications. Standards & Specifications Parameter Details Standards DIN 580 (eye bolts) / DIN 582 (eye nuts) Material Standard C15E (1.1141) case-hardening steel Thread Types Metric coarse (standard) / Metric fine / UNC / BSW (on request) Thread Tolerance 6g (metric) Surface Finish Zinc plated, blue passivated (A2K) / Hot-dip galvanized (HDG) / Plain / Stainless steel available DIN 580 specifies the characteristics of steel and stainless steel eye bolts for hoisting operations, as part of slings and as a load-suspension device. DIN 582 specifies equivalent requirements for lifting eye nuts. CE marking: As mobile lifting equipment, eye bolts and eye nuts within the European Union require CE marking in accordance with the Machinery Directive (EC Directive 2006/42/EC).
