Product Features
Made from heat-treated material meeting Grade 8.8 standards, offering excellent tensile and shear strength. Suitable for heavy-duty applications, vibration-prone environments, and critical structural connections.
Manufactured in strict accordance with DIN 934 tolerances, ensuring perfect compatibility and interchangeability with bolts and screws of the same grade.
The electro-galvanized coating enhances corrosion resistance, making it suitable for general industrial environments both indoors and outdoors, and more durable than uncoated or blackened versions.
DIN 934 Grade 8.8 galvanized hex nuts feature precision-tapped surfaces with complete thread profiles, ensuring smooth engagement. They are resistant to stripping and loosening, providing high assembly reliability.
Applications
- Construction machinery, machine tools, automotive chassis and frames
- Steel structures, bridges, curtain walls, lifting equipment
- Molds, automated equipment, power units
- Industrial assemblies with high requirements for joint strength and corrosion resistance
