Screw wire thread insert manufacturer Tangless thread insert

Tangless thread insert is a new type of threaded insert developed on the basis of common wire threaded insert. Tangless thread insert overcomes the shortcomings of traditional threaded insert installation shanks and low installation efficiency, the slotted part of traditional threaded insert installation shankks can not be controlled accurately, resulting in the tail is not easy to break or too easy to break the phenomenon of the tail end is easy to protrude when removing the shank, affecting the screw-in screw threads, which seriously affects the quality of the product, and the tail end is not easy to clean up after removing the tail end, which easily results in After the removal of the tail is not easy to clean, easy to cause stagnation, will seriously affect the quality of the whole product.

At the same time, the traditional steel wire thread insert seriously affects the production efficiency when installing the shank, and the installation is slow. Tangless thread insert use threaded rotary hook-up installation tools, taking into full account the efficiency of the installation, the installation does not need to go to the shank, non-directional.

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 colours 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 resistance has high requirements, you can consider tin-plated coating of steel wire threads.

6. Dry film lubrication for mild corrosion or high temperature environment.

1.Assembly <Improve the performance of internal thread connection>:
Embed the steel wire thread insert on metal or non-metallic materials to form a high strength, wear-resistant, interchangeable standard internal thread. Applied to aluminium, magnesium, copper alloy, plastic, organic glass, plywood and other low-strength engineering materials, it can significantly improve the strength and wear resistance; applied to steel, cast steel, cast iron, it can improve the durability of the screw , prevent the screw from loosening due to a variety of vibrations caused by the screw to fall, fatigue rupture and to improve the fatigue strength of the screw in the connection.

2.Conversion <metric and imperial thread conversion>:
the use of steel wire thread insert for metric ← → inch system ← → international standard threaded hole conversion, very convenient, fast, economical, practical, applicable to any import and export products.

3.Repair <internal thread repair>:
In the event of thread processing errors or repair of damaged internal threaded holes, the use of steel wire threaded bushings as a means of repair can be obtained without increasing the weight and volume of the repair economically to save the important parts, fast and effective repair to the original state, while also meeting or exceeding the original technical requirements.
