DIN 985 304 Carbon steel Gr4.8 Zinc Hex Nylon Insert Lock Nuts For
1. Product Description
General nut in the use of the process due to vibration and other
reasons will be loose, in order to prevent this phenomenon, so the
invention of self-locking nut. Self-Locking nut Its function is
mainly to prevent loose, anti-vibration. For special occasions. Its
working principle is usually by friction self-locking. The type of
self-locking nut, which is classified by function, has a nylon
ring, a neck, and a metal loosening device. They all belong to the
effective torque type of anti-pine nut self-locking nut is
generally rely on friction, the principle is through the embossing
teeth into the sheet metal preset hole, the general square hole
aperture slightly smaller than the rivet nut. The use of nuts and
locking mechanism connected, when tightening the nut, locking
mechanism lock ruler body, ruler frame can not be free to move, to
achieve the purpose of locking; When the nut is loosened, the
locking mechanism is removed and the ruler is moved along the
High-strength self-locking nut is a classification of self-locking
nut with high strength and strong reliability. Mainly the
introduction of European technology as a prerequisite for
road-building machinery, mining machinery, vibration machinery and
equipment, domestic production of such products are very few
Nylon locking nut is a new type of high vibration elastic solid
parts, can be applied to the temperature - 50 ~ 100 ℃ of various
mechanical and electrical products.
Aerospace, aircraft, tanks, mining machinery, automobile transport
machinery, agricultural machinery, textile machinery and electrical
products and all kinds of machinery, the demand for nylon locking
nut, it is because it ant-vibration locking performance compared
with other kinds of locking device, and the vibration lifespan is
several times or even more higher.
root mother, pine nuts, satisfied that the child.
2. Application: locking connector through the wire, or other tube.
Nut works by using friction between the nut and bolt self-locking.
However, in such a dynamic load lock reliability is reduced. In
some important occasions and we'll take some anti-loosening
measures to ensure the reliability of the locking nut. Locknut is
one of them against rotation.
Lock nut anti-loosening effect depends on the merits of a nut and
bolt engaging interaction between threads. Currently engaging way
to improve the interaction between the threads there are many, such
as structural improvements Spiralock thread nut, nylon nut nylon
increasing roughness, surface treatment, thread and the like.
High-strength self-locking nut for marine and bridge, it can
convert friction into the expansion force between bolt and groove
nut to achieve excellent self-locking effect. There are two slots
in the upper part of the ESL nut, when the nut is tightened on the
bolt, the thread of the bolt will be screwed into the narrow groove
of the Nut cross section, and the thread is gradually locked by the
nut side wall to achieve the self-locking function. The exquisite
production process can keep the torque type of the locking element
consistent, products are generally used in railway casting, rail
transit, transmission systems, mining equipment, highways,
military, oil production machinery, automotive industry, public
facilities, subways, engines, construction machinery, aerospace,
drilling equipment, bridges, generators, agricultural machinery,
shipbuilding industry , metallurgical equipment, trains,
compressors, medical machinery, signal systems, wind power
Advantage one, strong abrasion resistance and shearing ability: nut
thread tooth bottom 30 degree bevel can make the nut locking force
evenly distributed in all the teeth, because of each tooth thread
surface pressure distribution evenly, so the nut can better solve
the problem of thread wear and shear deformation. Advantage two,
repeated use of good performance: a large number of use shows that
the nut after repeated fastening and dismantling, the locking force
is still not reduced, can maintain the original locking effect.
Advantage three, Superior anti-vibration performance: When screwed,
the thread of the top thread of the bolt tightly enters the NUT's
30° wedge-shaped bevel and is clamped, and the normal force exerted
on the wedge-shaped incline is the angle of 60° between the bolts
and the axis of the bolt. Anti-loose nuts are produced when the
normal force is much larger than the common standard nut, has a
great anti-loosing ability.
