M3 * 0.5 Thread Protect And Repair Stainless Steel Thread Inserts
Information
Wire thread insert is a new type of internal threaded fastener,
suitable for threaded connection. It is screwed into and fastened
in the threaded hole of one of the connected parts to form a
standard internal thread. The bolt (or screw) is then screwed into
it. Also known as threaded wire sleeve, wire sleeve for short. It
is a high-strength, high-precision, smooth surface of the
cold-rolled stainless steel wire precision diamond machining made
of a spring-like member concentric with and external thread, used
to enhance the protection of the internal thread and of a
low-strength material. The principle is formed between the screw
thread and the elastic connecting base body, thread manufacturing
to eliminate errors and improve the bonding strength. A threaded
hole embedded wire thread insert engineering materials low strength
aluminum, magnesium alloy, iron, steel, glass, plastic and the
like, can be accurately formed in accordance with international
standards of thread, having a high connection strength, shock,
impact and wear-resistant Function, and can disperse stress to
protect the base thread, greatly extend the service life of the
base, and is widely used in electronic applications.
The wire thread insert is made of high-hardness,
corrosion-resistant steel wire with a diamond-shaped cross-section.
It is a spring-like concentric body of internal and external
threads. The cross-sectional shape of the standard internal thread
used for fastening parts is a combination of two internal and
external threads. Wire thread inserts are divided into two types:
ordinary type and locking type, each with or without breaking
grooves and with breaking grooves.
Feature
1. Wire thread inserts are used in various low-strength materials,
which can greatly improve the wear resistance of screw connections
and avoid damage to the connecting threads.
2. Due to the certain elasticity of the wire thread insert, the
load distribution on each circle of the thread can be more uniform,
eliminate the pitch and tooth form deviation between the screw and
the screw hole, and can absorb vibration, thus improving the
connection strength and resistance of the thread. Fatigue strength.
3. The locking wire thread insert can lock the screw in the
threaded hole, so that the screw will not loosen when it is
subjected to shock and vibration, which is better than the normal
locking device.
4. Compared with the method of inserting steel or copper bushings,
under the same strength conditions, screws with smaller size and
higher strength can be selected, which can reduce the volume and
reduce the weight.
5. The hardness of the wire thread insert is higher than that of
the screw, so it is less worn during the assembly and disassembly
process of the screw connection and can be used repeatedly.
According to relevant experimental studies, the tensile strength of
the wire thread insert is more than 7 times that of the screw, so
the wire thread insert will not be damaged even if the screw is
broken.
Application
In addition to aerospace and military applications, wire thread
inserts are also widely used in civil products such as railway
transportation, construction machinery, textile machinery, medical
equipment, papermaking, weapons, radar, rockets, ships, steam
turbines, and chemicals. In other countries, it is not only used in
aircraft, aerospace industry, but also used in ships, automobiles,
machine tools, electrical machinery, textile machinery and other
industrial and instrumentation. Even in camera, sewing machine,
modular furniture and other light industrial products, but also
widely used in this wire sets.
