Product Description:

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
1. 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.
2 Internal thread: K-nuts are threaded internally for use with screws or bolts.
3. 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.
4. Function

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.

1.ISO Standard: ISO 4032: Hexagonal thin nuts-Product grade AISO 4033: Hexagonal thin nuts-Product grade B

2.DIN standard (German Industrial Standard) DIN 439: Hexagonal thin nuts

3.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.

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.

One of the advantages of the k-lock nut is that it provides greater preload, which reduces the likelihood of loosening. Since the slope of the threaded rod interacts with the slope of the nut, as the nut rotates, the slope pushes the threaded rod, causing it to move forward. This forward movement creates a torque that tightens the nut even more. As a result, the k-lock nut stays tight when subjected to vibration, shock or other external forces, reducing the risk of the nut loosening.
Another advantage is the reusability of k-lock nuts. Since the locking principle of the k-lock nut is based on the action of slopes and friction rather than deformation or damage, it can be used many times without losing its locking effect. This makes the k-locking nut a cost-effective connecting element.

Applications
K-nuts have some unique features and advantages over hexagonal nuts, and the following are their main differences:
1. Structure and appearance:
K-nuts: K-nuts have a K-shaped appearance and look like the letter K when viewed from the side. they usually have two semi-circular openings.
Hexagonal Nuts: Hexagonal nuts have a hexagonal appearance with six flat sides and six corners.

2. Locking properties:
K-Nuts: K-nuts are designed to provide additional locking force. Their special structure allows them to clamp more tightly to the bolt or screw, reducing the risk of loosening.
Hexagonal Nuts: Hexagonal nuts provide a basic tightening function, but are usually less effective than K-nuts in preventing loosening.

3. Installation and removal:
K-nuts: K-nuts have two openings, which makes them easier to install and remove than hexagonal nuts, without having to completely disengage the nut.
Hexagonal nuts: Hexagonal nuts require the use of a spanner or spanner to tighten and remove them and usually require more space.

4. Areas of application:
K-Nuts: K-Nuts are typically used in applications where there is a need to prevent vibration or external forces from loosening the bolt or screw, such as mechanical engineering, automotive manufacturing, construction and aerospace.

Hexagonal Nuts: Hexagonal nuts are widely used in a variety of general fastening applications, including home assembly, carpentry and general mechanical assembly.

5. Special requirements:
K-Nuts: Due to their locking properties, K-nuts are useful in situations where secure fastening and prevention of loosening is required.

Hexagonal Nuts: Hexagonal nuts are suitable for general use without special locking requirements.

Overall, K-nuts are useful in situations where extra locking force is required, and their unique construction and properties make them excellent for specific applications. However, hex nuts are still a common choice for most general fastening applications. The choice of nut type should be based on the needs and requirements of the specific application.

Galvanising is a surface treatment technique of plating a layer of zinc on the surface of metals, alloys or other materials to provide a beautiful and rust-resistant appearance. The colour of zinc after galvanising is silver-white, and the colour after passivation of galvanising can be white, coloured, army green, etc.
