Some comparison of wire thread insert, self-tapping thread insert and Key locking thread insert

First is the wire thread insert

The steel wire thread insert is made of high quality austenitic stainless steel material, and forms reliable internal thread after installation and embedding. It can significantly improve the strength and wear resistance on low strength engineering materials such as aluminum, magnesium, copper alloy, plastics, plexiglass and rubber board. Applied to steel parts, cast steel, cast iron, can improve the durability of screws, prevent screws loose due to various vibration caused by fatigue fracture and improve the fatigue strength of screws in connection. The advantages of the wire thread insert are: high wear-resisting tensile strength, low thread friction, high surface quality, excellent anti-corrosion and heat resistance.

Second is the self-tapping thread insert

There are teeth inside and outside the self-tapping thread insert, embedded in plastic, aluminum alloy, cast iron, copper and other soft materials, can form a higher strength of the internal thread hole, self-tapping thread insert can also repair the broken internal thread.

Self-tapping thread insert has self-tapping ability, the base material does not need to tap teeth in advance, saving cost.

The contact surface with the finished product is large, the tensile force is strong, and the material of lower strength can be used in the design of the product.

For the female thread that has been worn out or broken, the same screw can be used again with the self-tapping insert.Strong resistance to vibration, can prevent loosening.

After the installation of the self-tapping insert, there is no clearance with the base material, and if the base material contains bubbles, it also has good air tightness.

Self-tapping thread insert installation is simple and rapid, only one assembly tool, low cost, almost no defect rate.The material of self-tapping thread insert is generally carbon steel and stainless steel. Carbon steel can be plated with color zinc, yellow zinc, blue and white zinc.

Finally Key locking thread insert

It is especially suitable for application in the environment requiring high strength internal threads, which can effectively resist earthquake and draw.

Compared with the wire thread insert, the strength of the thread hole can be enhanced more effectively.

The bolt thread insert is mainly made of stainless steel material, and the specification also has the metric inch size;

Simple to use, easy to install and operate.
