Customized Kep nuts
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
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.
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.
