DIN 985 vs ISO 10511
Nylon Insert Lock Nut
- Interchangeable
- Yes. Same thread. The wrench size is 1 mm smaller at M10, M12 and M14 in ISO 10511; the nut is lower in ISO 10511 at 10 sizes (M16: 16 mm in DIN 985, 12.42 mm in ISO 10511).
- Which to order
- ISO 10511 for new drawings. It replaced DIN 985, and if your drawing says DIN 985, we make DIN 985.
- Sizes
- M3 to M36 in both. DIN 985 also has M7, M18, M22 and M27 and more.
