Is DIN 934 still current?
No, it has been replaced. DIN 934 has been replaced by ISO 4032 (MechAtlas review: 27 October 2026). Use the replacement for new work, and check differences before interchanging parts.
What it covers
Former German hex nut standard.
Before you interchange parts
- DIN 934 → ISO 4032 (2023): ISO nut taller; AF changes
- DIN 934 → ISO 4032 / EN ISO 4032 (stated by catalogue): Catalogue prints 'in compliance with ISO 4032'. ISO 4032 nut is taller and has the ISO 272 across flats for M10/M12/M14/M22. Fine-thread equivalent is ISO 8673.
