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 chipping.

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 service life.

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.

6. Anti-loosening:

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.

Installation inspection

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.
