Product Description
Stainless steel K nut product illustration

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.

Structural Features
  • 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
Key Advantages
  • 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
Industry Standards
  • 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)

Feature K-Nuts Hexagonal Nuts
Structure K-shaped profile with dual openings Standard hexagonal shape
Locking Performance Superior vibration resistance Basic tightening function
Installation Easier mounting with dual openings Requires complete engagement
Applications High-vibration environments (automotive, aerospace) General fastening purposes
