Product Overview
Product Application
DIN 934 hexagon nuts are one of the most widely used metric nuts in mechanical fastening systems. Featuring a standard six-sided design and internal metric thread, they provide reliable torque transmission and secure connections when paired with matching bolts or threaded rods.
Although DIN 934 has been replaced by ISO 4032 in newer standard systems, DIN 934 hex nuts remain widely available and commonly used in global fastener markets.

DIN 934 vs ISO 4032 – Key Differences
Although DIN 934 and ISO 4032 hex nuts are widely interchangeable, several dimensional differences should be considered during global sourcing:
1. Wrench Size Difference
- ISO 4032 reduces the across flats (SW) dimension by 1 mm on specific sizes.
- Example: M10 nut
- DIN 934: 17 mm SW
- ISO 4032: 16 mm SW
- Pay attention to tool compatibility and assembly space.
2. Nut Height Difference
- ISO 4032 nuts are slightly higher than DIN 934 nuts.
- The increased height provides:
- Better thread engagement
- Improved load distribution
- Slightly higher mechanical performance
3. Replacement Considerations
- DIN 934 and ISO 4032 are generally interchangeable for standard applications.
- For OEM equipment or precision assemblies, always confirm:
- Wrench size
- Nut height
- Assembly drawings
Summary:
DIN 934 remains widely used in traditional markets, while ISO 4032 is the modern international replacement standard with minor dimensional improvements.
Product Advantages
High Torque Performance
The hexagonal shape provides excellent wrench engagement, allowing secure tightening without damaging the fastener.
Easy Replacement & Maintenance
As one of the most common metric nut standards, DIN 934 nuts are easy to source and replace worldwide.
