LONGZE high-precision ISO 4032 Hexagon Nuts (Style 1) represent the modern international standard for regular metric nuts, meticulously engineered for superior structural integrity. As a core component of the LONGZE GFM-WCR System, these nuts are designed with a slightly increased height compared to legacy DIN 934 standards, significantly enhancing thread engagement and providing exceptional resistance against stripping in critical joints.
Manufactured in high-grade carbon steel (Property Classes 8, 10, 12) and premium stainless steel (A2/A4), our ISO 4032 nuts are optimized for automated assembly lines and high-vibration environments. Whether utilized in photovoltaic brackets, electrical installations, or heavy steel structures, LONGZE ensures each fastener meets rigorous global engineering specifications for maximum safety and reliability.

Frequently Asked Questions
ISO 4032 (Style 1) offers a greater nut height than DIN 934, which directly increases the stripping strength of the thread. This makes it the preferred choice for safety-critical and high-load engineering joints.
No. Specifically for sizes M10, M12, and M14, the width across flats differs between ISO 4032 and DIN 934. We recommend verifying your tooling and clearance requirements during the transition.
We provide carbon steel in Property Classes 8, 10, and 12, as well as stainless steel grades A2 and A4, ensuring suitability for everything from general construction to corrosive environments.
Every batch undergoes rigorous proof load verification per ISO 898-2 and chemical composition analysis. We provide Batch-Specific MTC 3.1 certificates for full transparency.
Yes, we offer a variety of surface treatments including Electrolytic Zinc (Cr3+), Zinc Flake (ISO 10683), and Passivation for stainless steel to meet specific salt-spray resistance requirements.
Absolutely. Our engineering team provides expert consulting on Dimensional and Technical Property Mapping to ensure your project remains compliant across ISO, DIN, and ASME standards.
