The K Nuts series comprises stainless steel DIN 6926 hex flange nuts equipped with non-metallic locking inserts, engineered to provide secure fastening in high-vibration environments. These metric lock nuts integrate a flanged base that functions as an integrated washer, distributing clamp load over a wider surface area while eliminating the need for additional hardware. Manufactured in full compliance with DIN 6926 standards, these K Nuts deliver enhanced reliability for industrial, automotive, and mechanical applications.
Featuring a permanent nylon ring insert within the threaded portion, these K Nuts effectively grip the mating screw or bolt to prevent loosening under dynamic loads. The elastic nature of the nylon collar ensures consistent locking force throughout the nut’s service life, maintaining preload and resisting vibrational loosening. This design is particularly advantageous in applications where safety and reliability are critical, such as automotive assemblies, machinery, and structural frameworks.
Available in both smooth and serrated flange variants, the K Nuts offer additional flexibility in locking mechanisms. The serrated version provides an extra anti-rotation feature by biting into the contact surface, further enhancing resistance to vibration-induced loosening. Both types are manufactured from high-grade stainless steel, ensuring excellent corrosion resistance and durability even in harsh operating conditions. This versatility makes the K Nuts suitable for a wide spectrum of industrial and engineering applications.
Certified to meet international mechanical and material standards, these lock nuts are designed for use in precision assemblies where failure is not an option. The flange design not only improves bearing surface contact but also reduces surface pressure, helping to protect softer materials from damage during installation. This combination of features ensures that the K Nuts provide long-term performance without compromising the integrity of joined components.
The DIN 6926 K Nuts represent a robust and innovative fastening solution that merges the benefits of a flange nut with the reliability of a non-metallic locking element. Their dual locking mechanisms—through either nylon insertion or serrated flange—make them an intelligent choice for engineers and designers seeking to improve assembly security and performance in challenging environments.
