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.

Applications

Cold Galvanising
Cold galvanising, also called electro-galvanising, is the use of electrolytic equipment will be fittings after degreasing, pickling, after the composition of zinc salts into the solution, and connected to the negative electrolytic equipment, the opposite side of the fittings placed zinc plate, connected to the positive electrolytic equipment connected to the power supply, the use of electric current from the positive electrode to the negative electrode of the direction of the movement of the fittings will be a layer of zinc deposition, cold galvanised fittings are processed first after the galvanisation.
1,Principle
As zinc in dry air is not easy to change, and in the humid air, the surface can generate a very dense zinc carbonate film, this film can effectively protect the internal no longer subject to corrosion. And when some reason to make the plating damage and reveal not too large base, zinc and steel substrate to form a microcell, so that the fastener substrate to become the cathode and be protected. Widely used in automotive transport and other industries, but the need for trivalent chromium passivation layer, zinc-nickel alloy plated closed coatings to reduce the hexavalent chromium passivation harmful and toxic layer.
2,Performance characteristics
Zinc plating layer is thicker, the crystallization is meticulous, uniform and non-porous, good corrosion resistance; electroplating zinc layer is purer, slower corrosion in acid, alkali and other mists, can effectively protect the fastener substrate, zinc plating layer by chromic acid passivation after the formation of white, colour, military green, etc., beautiful and generous with a certain degree of decorativeness, due to the zinc plating layer has a good ductility, so it can be cold punched, rolled, bent and other kinds of molding and do not damage the The galvanised layer has good ductility, so it can be cold punched, rolled and bent without damaging.
3,Application scope
Zinc plating involves more and more extensive areas, fasteners have been used throughout the machinery manufacturing, production of galvanised hooked wire mesh, electronics, precision instruments, chemical industry, transportation, aerospace, etc. in the national economy is of great significance.

Has a thick dense pure zinc layer covering the surface of steel fasteners, it can avoid the steel substrate and any corrosive solution contact, protect the steel fastener substrate from corrosion. In the general atmosphere, the surface of the zinc layer forms a very thin and dense zinc oxide layer surface. It is very difficult to dissolve in water, so the steel fastener substrate plays a certain protective role. If zinc oxide and other components of the atmosphere to generate insoluble zinc salt, the anti-corrosion effect is more ideal; with zinc - iron alloy layer, combined with dense, in the marine salt spray atmosphere and industrial atmosphere in the performance of the unique corrosion resistance; due to the combination of solid, zinc - iron mutual solubility, with a strong wear resistance; due to the zinc has good ductility, the alloy layer and the steel substrate adhesion. Because of the good ductility of zinc, the alloy layer is firmly attached to the steel substrate, so hot-dip galvanising can be used for cold punching, rolling, drawing, bending and other moulding processes without damaging the plating layer; hot-dip galvanising of steel structural parts is equivalent to an annealing process, which can effectively improve the mechanical properties of the steel substrate, eliminate the stresses of the steel parts moulding and welding, which is conducive to the steel structural parts for turning; the surface of the hot-dip galvanising of the fasteners is bright and beautiful; pure zinc is the most plastic layer of the hot-dip galvanising. The pure zinc layer is the most plastic layer of zinc, its nature is basically close to pure zinc, with good ductility.

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.
