Product Description
K-nuts (also known as K-caps or flower tooth nuts) feature a specialized locking structure designed to prevent loosening under vibration or stress. These high-strength Grade 8.8 fasteners incorporate a movable flower tooth piece pressed into the hexagonal nut through stamping, utilizing elastic tension and anti-slip teeth for superior locking performance.
Key Features
- K-shaped profile with two semi-circular openings for easier installation
- Precision locking mechanism creates radial force through thread friction
- Reduced thread wear extends bolt/screw lifespan
- Available in galvanized zinc plating for corrosion resistance
- Customizable sizes and finishes to meet specific requirements
Structural Advantages vs Hexagonal Nuts
Locking Performance: K-nuts provide superior vibration resistance compared to standard hex nuts
Installation: Two openings allow partial engagement/disengagement without complete removal
Applications: Ideal for high-vibration environments in automotive, aerospace, and heavy machinery
