**DIN 7967 Self Locking Tight Nuts**
Made from high-quality spring steel (65Mn), these nuts are designed for reliable performance in challenging environments. Available in a range of coatings including White Zinc, Yellow Zinc, and Hot-Dipped Galvanization (HDG), they provide excellent corrosion resistance.
They are suitable for both metric sizes (M4 to M80) and inch sizes (#10 up to 2 inches). These self-locking nuts are ideal for applications where vibration resistance is essential, especially in tight or hard-to-reach spaces. Their unique design allows them to flex under load and return to their original shape, ensuring a secure and lasting connection.
Customized options are available upon request. For more information, visit **www.hexnuts.cn** and explore our full product catalog.
**About Self Locking Counter Nuts**
Self-locking counter nuts are manufactured from sheet metal and feature a spring-like structure that helps maintain a tight grip even under vibration. They can be tightened using an internal wrench, making them perfect for use in confined areas. This design ensures a strong, vibration-resistant fastening solution without the need for additional locking mechanisms.
