Product Overview This product line consists of stainless steel lifting eye bolts (DIN 580) and lifting eye nuts (DIN 582) manufactured from AISI 304 (A2) austenitic stainless steel. The eye bolts feature a forged ring-shaped head with an external threaded shank, while the eye nuts have an internal threaded base with an integral ring. Both are produced to DIN 580 / DIN 582 dimensional standards and are available in thread sizes from M6 to M36 (larger sizes on request). The AISI 304 stainless steel construction provides excellent corrosion resistance for general industrial, chemical, food processing, and non-coastal outdoor applications. The safety factor is 4:1 to 6:1 depending on manufacturer and configuration, with each unit permanently marked with the Working Load Limit (WLL), thread size, and CE marking. Material & Standard Compliance Parameter DIN 580 Eye Bolt DIN 582 Eye Nut Material AISI 304 (A2) stainless steel AISI 304 (A2) stainless steel Manufacturing Forged, polished Forged, polished Surface Blank / Polished (natural stainless) Blank / Polished Standard DIN 580 / Similar to DIN 580 DIN 582 Temperature Range −20°C to +200°C −20°C to +200°C Safety Factor 4:1 to 6:1 4:1 to 6:1 AISI 304 is a general-purpose austenitic stainless steel with 18–20% chromium and 8–10.5% nickel, offering excellent corrosion resistance and versatility in industrial environments. It is the most widely used stainless steel grade globally and provides superior corrosion resistance compared to carbon steel or zinc-plated alternatives. 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. The standard requires the thread of the assembly hole to be equal to the thread length of the pin, and the pin must be fully screwed up to the stop on the mounting surface.

Certifications for Central Asia & Middle East Export Saudi Arabia — SABER Certification Saudi Arabia has implemented the Technical Regulation for Machinery Safety – Part 3: Lifting Equipment (01-05-21-182). Approved by SASO, this regulation mandates that suppliers of lifting equipment and accessories demonstrate conformity before products are placed on the market. Lifting accessories including slings, hooks, and shackles are specifically covered. Requirements: PCoC (Product Certificate of Conformity) and SCoC (Shipment Certificate of Conformity) via the SABER platform Arabic language labeling for all safety instructions and warnings Certificates must be obtained before vessel arrival Local Saudi importer required for SABER application EAEU / Kazakhstan — EAC Certification For export to Russia, Kazakhstan, Belarus, Armenia, and Kyrgyzstan, lifting eye bolts fall under TR CU 010/2011 (Machinery Safety) . The EAC (Eurasian Conformity) certificate or declaration is mandatory for customs clearance and legal sale within the EAEU. Key requirements: EAC Certificate of Conformity (CoC) for lifting equipment — higher risk category Russian/Kazakh language documentation for labels and manuals Kazakh agent required for non-EAEU manufacturers GOST Standard Reference GOST 4751-73 is the Russian/CIS standard for eyebolts (рым-болты), covering their use for lifting, lowering, or holding loads during assembly and rigging operations. DIN 580 is widely recognized as an analogue to GOST 4751-73 in the CIS market.

For any lift exceeding a 15-degree angle, the working load limit must be reduced according to the load table, and shoulder-pattern eye bolts should be considered for angular lifts. Eye bolts must be fully screwed in until the collar seats flush against the mounting surface, and the tapped hole depth must accommodate the full thread length.
