DIN 934 vs ISO 4032
Hex Nut
- Interchangeable
- Yes. Same thread. The wrench size is 1 mm smaller at M10, M12 and M14, 2 mm larger at M22 in ISO 4032; the nut is taller in ISO 4032 at 15 sizes (M18: 15 mm in DIN 934, 15.8 mm in ISO 4032).
- Which to order
- ISO 4032 for new drawings. It replaced DIN 934, and if your drawing says DIN 934, we make DIN 934.
- Sizes
- M5 to M36 in both. DIN 934 also has M1.6, M2, M2.5 and M3 and more. ISO 4032 also has M7 and M39.
