K-nuts, also known as K-caps or flower tooth nuts, are specialized fasteners designed for locking and preventing loosening. These nuts feature a movable flower tooth piece pressed into one end through a stamping process.
During the locking process, the elasticity of the floral teeth and their anti-slip properties create effective locking and anti-loosening capabilities. K-type axial precision locking nuts utilize free friction locking principles to secure workpieces, generating radial force between threads for reliable fixation.
- K-shaped profile: Side view reveals a distinctive K-shape contour
- Internal threading: Designed for compatibility with standard screws and bolts
- Dual openings: Semi-circular openings facilitate easy clamping and release
- Enhanced locking: Superior resistance to vibration and external forces
- Simplified installation: Dual openings enable easier mounting than traditional hex nuts
- Reduced wear: Additional friction minimizes thread wear, extending fastener life
- ISO 4032/4033: Hexagonal thin nuts (Product grades A/B)
- DIN 439: Hexagonal thin nuts (German Industrial Standard)
- ANSI B18.2.2: Hexagonal thin nuts (American National Standard)
