The upper section forms a continuous lifting eye designed to receive a compatible hook, shackle or other approved connecting component. The connection must fit correctly inside the eye without point loading, binding or forcing.
The lower section contains an internal thread that engages a matching bolt, stud or shaft. Thread diameter, pitch, tolerance, engagement length and mating material must be confirmed for the assembly.
The base must seat fully and evenly against a suitable supporting surface. Incomplete seating, contamination, burrs or an uneven contact face can introduce unintended bending and reduce the reliability of the assembly.

A DIN 582 eye nut is threaded onto a suitable male thread until its base is correctly seated. An approved lifting accessory is then connected through the eye. The eye nut, mating thread, supporting component, lifting accessory and load path must function as one engineered system.
The rated capacity cannot be determined from appearance or nominal thread size alone. Any permitted load value must correspond to the exact product size, material, installation method, load direction and applicable safety requirements.
Subject to engineering approval, DIN 582 eye nuts may be considered for:
lifting or positioning machinery components;
handling fabricated metal parts;
equipment installation and maintenance;
temporary attachment points on threaded studs;
production fixtures and material-handling systems;
construction and assembly operations;
transport preparation where the eye nut is specifically approved for the intended restraint function.
Application examples do not establish a safe load rating. Each lifting operation requires a suitable risk assessment and lifting plan.
The internal thread must match the mating component in diameter, pitch and tolerance. Cross-threading, insufficient engagement or damaged threads can lead to failure.
Load direction has a major effect on eye-nut performance. Do not assume that a capacity for straight loading also applies to angular or side loading. Use only the directions and reductions permitted by the applicable product data and lifting procedure.
The bolt, stud, shaft or threaded anchor must be capable of transferring the intended force into the supporting structure. The eye nut cannot compensate for an undersized or unsuitable mating component.
The base should seat completely on a flat, clean and sufficiently strong surface. The eye should align with the intended force path without being loosened to obtain orientation unless an approved method specifically allows it.
Corrosion, chemicals, temperature, wear and repeated loading can affect suitability. The required steel grade, galvanizing specification and inspection interval should be selected for the actual environment.
Verify the product identification, thread and approved load data.
Inspect the eye, base and internal thread for cracks, deformation, wear or corrosion.
Inspect the mating thread and supporting surface.
Clean all contact and thread surfaces before installation.
Thread the eye nut fully onto the compatible mating component.
Ensure complete, even seating against the supporting surface.
Connect only a compatible and approved lifting accessory.
Apply the load smoothly and only in the permitted direction.
Keep personnel clear of suspended loads.
Remove the eye nut from service if damage, deformation or uncertain identification is found.
Installation and lifting operations must be performed by competent personnel under the applicable site rules and regulations.
Before each use, check for:
readable product and size identification;
cracks, distortion or an enlarged eye opening;
damaged, worn or corroded threads;
severe rust or coating loss;
burrs or damage on the bearing surface;
evidence of unauthorized welding, heating or machining;
correct seating and thread engagement;
compatibility with the hook, shackle or connector;
confirmation that the planned load and direction are permitted.
Never exceed the confirmed working load for the exact product and configuration.
Do not use an unverified catalog value as a lifting authorization.
Do not apply side or angular loading unless explicitly permitted.
Do not shock-load, weld, grind, heat or reshape the eye nut.
Do not insert hooks or connectors that cause point loading or binding.
Do not use damaged, modified or unidentified lifting components.
Do not stand or work beneath a suspended load.
No. Capacity varies with size, material, manufacturing condition, thread engagement, load direction and installation. Use only confirmed technical data for the exact supplied item.
Angular or side loading must not be assumed. Confirm the permitted direction and any required load reduction before use.
The supply scope must be confirmed in the quotation. The mating bolt or stud requires its own material, thread and strength specification.
No. The galvanizing method, coating thickness, appearance and corrosion requirement should be stated when they are important to the project.
A lifting eye nut should not be welded, heated, straightened or reshaped for reuse. Remove damaged components from service and follow the applicable inspection procedure.
For a technical quotation, provide the thread size and pitch, required quantity, material and finish requirement, load and load direction, mating component details, operating environment, applicable inspection requirements and destination.
