Product Overview
K Nut product illustration
K-nuts, also known as K-caps or flower tooth nuts, are nuts with a special structure whose main function is to lock and prevent loosening. K-nuts are characterised by a movable flower tooth piece pressed into one end of the hexagonal nut by means of a stamping process.
During the locking process, the elasticity of the floral teeth and the anti-slip teeth of the floral teeth are used to achieve the purpose of locking and anti-loosening. K-type axial precision locking nuts achieve the fastening of the workpiece through the free friction locking principle. When the nut rotates, friction is generated between the threads and the workpiece, which results in radial force between the threads and thus achieves the fixing effect.
Structural Features
  • Appearance shape: The appearance of K-nuts is K-shaped, that is, when viewed from the side, its outline shows the shape of the letter K, hence its name.
  • Internal thread: K-nuts are threaded internally for use with screws or bolts.
  • Two openings: K-nuts have two openings, usually in the shape of a semicircle, which makes it easy to clamp or release the bolt or screw.
Functionality

Locking function: The K-nut is often used in applications where extra locking force is required. It is structurally designed so that the nut clamps onto the bolt or screw during tightening, providing additional resistance and thus reducing the risk of loosening. This is important for components that are subject to frequent vibration or external forces.

Easy installation: Because the K-nut has two openings, it is easier to install and remove versus a traditional hex nut without having to completely disengage the nut.

Reduced Thread Wear: Since the K-nut provides additional friction, it reduces thread wear, thereby extending the life of the bolt or screw.

Industry Standards
  • ISO Standard: ISO 4032 (Hexagonal thin nuts-Product grade A), ISO 4033 (Hexagonal thin nuts-Product grade B)
  • DIN standard (German Industrial Standard) DIN 439: Hexagonal thin nuts
  • ANSI/ASME standard: ANSI B18.2.2 (Hexagonal thin nuts)
These standards typically specify requirements for dimensions, thread specifications, materials, finishes and properties of K-nuts. The specific standards that apply depend on your country and industry.
Installation Method
When using a k-lock nut, it is first fitted to a bolt or threaded rod, and then by rotating the nut, it creates a tight contact with the threaded rod. As the nut rotates, the slope interacts with the slope of the threaded rod, and the ramp of the slope contacts the threads of the rod, creating a friction force. This friction prevents free rotation of the nut and provides additional locking force.
Comparison with Hexagonal Nuts
Feature K-Nuts Hexagonal Nuts
Structure and appearance K-shaped appearance with two semi-circular openings Hexagonal appearance with six flat sides
Locking properties Provides additional locking force, reduces loosening risk Basic tightening function, less effective in preventing loosening
Installation and removal Easier to install/remove due to two openings Requires spanner and more space
Areas of application Vibration-prone applications (mechanical, automotive, aerospace) General fastening applications
