Stainless Steel Metal M5 * 0.8 Wire Thread Insert For Thread Repair
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.
The locking type is a polygonal locking ring with one or more turns
added to the ordinary threaded sleeve. The elasticity of the
locking ring has a braking effect on the screw. The locking type
wire thread insert has all the advantages of the ordinary type wire
thread insert, does not affect the installation of the screw, and
only increases the appropriate torque during installation.
It is divided into two types: ordinary type and locking type, which
can be screwed into threaded holes of metal or non-metal materials
to form high-strength, wear-resistant, high-temperature,
shock-resistant, impact-resistant, and corrosion-resistant standard
M, MJ Thread, and can disperse the stress, protect the thread of
the base body, can comprehensively improve the performance of the
screw hole, and prolong the service life of the machine part.
1. Increase the connection strength:
It can be used for light, soft and low-strength alloy materials
such as aluminum and magnesium, wood, plastic, rubber and other
easily deformable and low-strength materials to avoid slippage,
wire loss, and wrong teeth.
2. Increase the bearing surface:
It can be used for thin parts that require a strong connection
force but cannot increase the diameter of the screw hole.
3. Improve connection conditions:
The connection is tight, effectively preventing the phenomenon of
4. Wear resistance:
It can be used in parts that are frequently disassembled and
installed and screw holes that are frequently rotated to extend its
5. Anti-rust knot:
It can be used in chemicals, ships, vehicles, mines, mines, field
equipment, etc. It is suitable for use in harsh environments such
as humidity and corrosion, and is convenient for disassembly,
installation and maintenance.
It can be used in aerospace, aviation, military equipment and other
occasions that require high insurance coefficients.
7. Earthquake resistance:
It can be used for instruments, precision and valuable equipment
and power equipment.
8. For maintenance:
Simple example: Diesel and gasoline engine bodies, various aluminum
parts, lathe tool tables, etc. will be scrapped due to damage to a
screw hole. As long as the screw hole is re-tapped and the screw
sleeve is installed, the waste parts will come back to life without
loss of performance. Especially for large and expensive parts, its
economic value is more obvious.
After the wire thread insert is installed, the threaded hole
tolerance zone depends on the profile manufacturing tolerance of
the wire thread insert and the thread tolerance zone of the wire
thread insert mounting hole. The former is controlled by the wire
thread insert manufacturer, and the latter mainly depends on the
tapping of the wire thread insert mounting hole. The wire precision
usually forms 6H grade. When the precision is high, it can reach 5H
and 4H tolerance bands. The unified thread standard is 2B and 3B.
Corresponding level plug gauges can be used to detect the thread of
the bottom hole.
