Wire thread insert
Stainless Steel Wire Thread Inserts for Aluminium
Wire thread inserts technology
Thread inserts achieve a heavy-duty connection capability in low-strength metal materials and have been proven practice for over sixty years. These thread inserts, made from a well-proven and tested quality stainless steel are formed from rhomboid profiled wire into a resilient spiral. After installation the tang is broken off at the notch (pre-set break off point).
The latest generation for this technology is called AVIC-Flight Thread inserts
Due to its optimal fitting structural shape, installation has been made far more simple. This is guaranteed by the installation area, which facilitates that the AVIC-Flight Thread inserts can be utilised as a screw and screwed-in. The tool sleeve required until now with its leader cartridge is no longer necessary.
Only a fitting mandrel is now required for screwing-in. But the acceptable available structural form tools can still be utilised.

Surface treatment
For steel wire threaded inserts made of 304 stainless steel, the surface treatments available are：
1. No treatment, natural surface
2. Environmentally friendly colour plating, according to customer needs can be plated in purple, green, blue, red. In industries where large quantities of threaded inserts are required, colour plated wire threaded inserts help to identify whether they are installed or not. The different colors of the wire threaded inserts are also very convenient for visual management.
3. Cadmium plating, cadmium (cd) plated steel wire threaded inserts corrosion resistance, lubrication, wear resistance, electrical conductivity, electromagnetic properties, heat resistance is stronger.
4. Silver-plated, silver-plated steel threaded bushings can be installed in a variety of shell materials, including magnesium alloys, aluminium alloys and corrosion and heat-resistant materials, mainly used to reduce the screw threads in the high-temperature state of the bonding effect.
5. Tin-plated, tin-plated steel wire threads inserts have the biggest advantage of better corrosion resistance, for corrosion resistan0ce has high requirements, you can consider tin-plated coating of steel wire threads.
6. Dry film lubrication for mild corrosion or high temperature environment.
