Product Overview Lifting eye nuts (also known as ring nuts or eye nuts) are forged steel threaded lifting points designed to be screwed onto bolts, studs, or threaded rods to create a secure, certified lifting attachment point. Unlike eye bolts, eye nuts feature a female metric thread, making them ideal for applications where a threaded stud is already present or where the lifting point needs to be installed flush against a surface. Our lifting eye nuts are manufactured to DIN 582 standard — the German/European specification for forged steel ring nuts used in lifting and load securement applications. They are available in M6 through M16 (with larger sizes available upon request), finished with electro-galvanized zinc plating for corrosion resistance, and are suitable for vertical lifting only (load along the axis of the thread). Each eye nut is drop forged from C15E carbon steel, providing superior grain structure and strength compared to cast alternatives. They are marked with WLL, thread size, manufacturer code, and CE marking for full traceability and compliance. Standard & Compliance Parameter Specification Standard DIN 582 Material C15E carbon steel (EN 10084) Safety Factor 4:1 (Minimum Breaking Load = 4 × WLL) Temperature Range −20 °C to +200 °C Marking WLL, thread size, grade, manufacturer code, CE Finish Electro-galvanized (zinc-plated, Cr(VI)-free) Thread Type Metric coarse thread (right-hand) The eye nut must be fully screwed in, achieving firm contact between the two mating faces. The counter thread must be of an equal length and the base material of an equal strength to that of the nut. Loading must be applied in the direction of the thread axis — larger angles between slings than 90° are not tolerated.

Data sourced from DIN 582 technical tables. Note: M6 and M8 share identical ring dimensions (20 mm inside / 36 mm outside). M14 and M16 also share identical ring dimensions (35 mm inside / 63 mm outside), with M16 offering a higher WLL due to the larger thread engagement. Product Features Drop Forged C15E Carbon Steel — Closed-die forging delivers consistent material density, dimensional precision, and higher load capacity than cast or machined alternatives. DIN 582 Standard Compliance — Meets the dimensional and material requirements of the recognized European standard for lifting eye nuts. Electro-Galvanized Finish — Zinc plating provides good corrosion resistance for general industrial, indoor, and outdoor applications. Cr(VI)-free passivation for environmental compliance. Permanent Marking — Each eye nut is permanently marked with WLL, thread size, manufacturer code, and CE mark for traceability and inspection. Compact Design — The female-thread design allows direct mounting onto existing studs or threaded rods without the protrusion of an eye bolt, ideal for space-constrained applications. Temperature Stability — Maintains full WLL from −20 °C to +200 °C, suitable for a wide range of industrial environments. Applications Lifting eye nuts are widely used across industries including: Industrial Lifting & Rigging — Creating lifting points on threaded studs, eye bolts, and machinery components Construction & Infrastructure — Lifting and positioning steel structures, precast elements, and heavy equipment Mechanical Engineering — Permanent lifting points on machine tools, molds, and fabricated assemblies Transportation — Securing and lifting during shipping, towing, and load securement Energy & Utilities — Installation and maintenance of power transmission equipment, wind turbines, and pipeline systems Marine & Offshore — Deck lifting and mooring point attachment where vertical lifting is applicable Installation & Usage Guidelines Ensure full thread engagement — The eye nut must be fully screwed in until firm contact is achieved between the mating face of the eye nut and the bearing surface. The counter thread must be of equal length and strength to that of the nut. Vertical lifting only — DIN 582 eye nuts are designed for vertical lifting only (load applied along the thread axis). Angled lifting is not permitted with this standard. For angled lifting applications, consider Grade 80 eye nuts conforming to EN 1677-1. Surface condition — The bearing surface must be perpendicular to the thread axis and free from paint, dirt, or deformation that could prevent full contact. Inspection — Visually inspect before each use for thread damage, corrosion, cracks, or deformation. Do not use if any damage is evident. Do not modify — Never weld, heat, or machine the eye nut, as this will affect the heat treatment and load capacity. Quality Assurance All eye nuts are manufactured under strict quality control and can be supplied with the following documentation: Material test certificates (Mill Certificates) Proof load test reports Certificate of Conformity (CE) Third-party inspection reports (SGS, BV, TÜV) available upon request Ordering Information To place an order or request a quotation, please provide: Thread size (M6, M8, M10, M12, M14, M16, or larger) Quantity Surface finish (standard: electro-galvanized) Certification requirements Packaging preferences Specifications are subject to change without prior notice.

FAQ for Lifting Eye Nuts DIN 582 — Central Asia & Middle East Markets Below are the most frequently asked questions from buyers in Central Asia (Kazakhstan, Uzbekistan, Kyrgyzstan, etc.) and the Middle East (UAE, Saudi Arabia, Qatar, Kuwait, Oman), with standard answers. 1. Certifications & Standards Q1: What certifications are required to import DIN 582 eye nuts into Central Asian countries? A: For Kazakhstan and Kyrgyzstan (EAEU members), eye nuts fall under EAC certification requirements as lifting accessories. EAC certification is the mandatory market access requirement and is valid across all five EAEU member states (Russia, Belarus, Kazakhstan, Armenia, Kyrgyzstan). For Uzbekistan, EAC is not recognized — a GOST-UZ (O'z DSt) certificate of conformity is required. For Tajikistan and Turkmenistan, national certification (GOST-TJ / Turkmenistan national conformity) is required. Q2: What about Saudi Arabia and the UAE? A: For Saudi Arabia, lifting eye nuts are subject to SASO regulations under the SALEEM/SABER programme. A Product Certificate of Conformity (PCOC) and Shipment Certificate of Conformity (SCOC) are required for customs clearance. The SABER platform registration must be completed before shipment. For the UAE, DIN 582 eye nuts with CE marking are widely accepted by distributors and contractors. Major lifting equipment suppliers in the UAE stock DIN 582 eye nuts from M6 to M48 in forged carbon steel and stainless steel, with loads stamped and test certificates supplied. Q3: Is CE marking required? A: Yes. As lifting accessories under the EU Machinery Directive 2006/42/EC, eye nuts require CE marking for European market access. Our products are CE-marked in accordance with DIN 582. This CE marking is also widely recognized and accepted by buyers in the Middle East and Central Asia as evidence of compliance with international safety standards. 2. Product Specifications Q4: What is the difference between an eye nut and an eye bolt? A: An eye nut has a female metric thread (internal thread) and is designed to be screwed onto a male threaded stud, bolt, or rod. An eye bolt has a male thread (external thread) and is screwed into a female threaded hole. Eye nuts are preferred when a threaded stud is already in place or when the lifting point needs to sit flush against a surface. Eye bolts are used when drilling and tapping a hole is more practical. Q5: What is the safety factor of your DIN 582 eye nuts? A: Our DIN 582 eye nuts have a 4:1 safety factor — the Minimum Breaking Load (MBL) is at least 4 times the Working Load Limit (WLL). Some suppliers quote 6:1 for certain configurations; please specify your requirement if a higher safety factor is needed. Q6: Can the eye nut be used for angled lifting? A: No. DIN 582 eye nuts are designed for vertical lifting only (load applied along the thread axis). Angled lifting is not permitted with this standard. For angled lifting applications, Grade 80 eye nuts conforming to EN 1677-1 should be used instead. Q7: What is the temperature range? A: Standard DIN 582 eye nuts maintain full WLL from −20 °C to +200 °C. For applications outside this range, please consult our technical team. Q8: What material are the eye nuts made from? A: Standard production uses C15E carbon steel (EN 10084), a high-quality aluminum-killed steel suitable for forging and heat treatment. Stainless steel versions (A2/304 or A4/316) are available for corrosive environments upon request. 3. Pricing & Quotation Q9: What is your MOQ?
