Step by step
- Check the stud: Match the stud thread to d1; the stud must be long enough for the full nut height e.
- Seat the base: Screw the nut down until its base sits flat on a machined face.
- Check the angle: Rated load drops when the pull is off the stud axis; use maker data for your angle.
- Inspect: Do not use a nut with a bent eye, worn thread or damaged base.

Worked example: M16 eye nut
An M16 DIN 582 eye nut has a 35 mm base, a 63 mm eye with a 35 mm opening, and stands 62 mm tall. The threaded nut part is 13 mm high, so the stud needs at least that much full thread above the face.
Common problems
- Nut bottoms on the stud: the stud is too long or the thread runs out before the base seats.
- Only part of the thread engaged: the stud is too short for the nut height e.
- Eye will not line up with the sling: do not back the nut off to align it; use a swivel lifting point instead.
FAQ
What is DIN 582?
A forged lifting eye nut (Ringmutter) that screws onto a stud or bolt, the nut version of the DIN 580 eye bolt.
How is it different from DIN 580?
DIN 580 has a male threaded shank; DIN 582 has a female thread and fits on a stud. The eye sizes match.
Why is m dashed above M36?
Only one source gives m above M36.
Why no M64 to M100x6?
The DIN sheet lists them, but we found only one source with values, so they are left out.
Where are the load ratings?
Load ratings are not included. Use the DIN 582 table or maker data for your nut and sling angle.
