Why does Tangless thread insert cover break?

Tangless Thread Insert, is a new type of internal thread fastener. It is usually made of wire wound, in the shape of a spring type of high precision internal and external thread concentric body. The main function of the tangless thread insert is to strengthen and protect the internal thread of the low strength material. When the steel tangless thread insert is embedded in the thread hole of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, glass steel, plastic and so on, it can form high-precision internal thread in line with international standards, which has the characteristics of high connection strength, earthquake resistance, impact resistance and wear resistance, and can disperse the stress to protect the matrix thread, greatly extending the service life of the matrix. It is widely used in automotive, electronics, machinery, aerospace and other fields.

Recently, some friends have consulted about the breaking of the tailless steel wire sheath, do not know how to deal with and prevent the reasons for the breaking of the tailless steel wire sheath, in general, the tailless steel wire sheath is rarely broken. Because of its own tailless tangless thread insert wire is relatively hard. However, under certain circumstances, the tailless wire sheath will still break. So what are the main reasons for the breakage of the tailless steel tangless thread insert?

1.The raw material quality of the tailless steel wire sheath is poor, and the quality of the tailless steel wire sheath is poor. There are a lot of impurities, impure, resulting in insufficient hardness of the tailless steel tangless thread insert.

2.Production of tailless steel tangless thread insertprocess problems. For example, the tailless steel tangless thread insertwith eccentric head, and the Q value is too deep and the R position design is too small during the punching operation in the production.

3.When the customer uses the tailless steel tangless thread insert, the force is too large. Usually you do a torque test to see what the breaking force is, and then adjust the torque.

Of course, there are more than three reasons for the breakage of the tailless tangless thread insert. However, the above three reasons are the main reasons for the breakage of tailless steel tangless thread insert. When it is found that the tailless tangless thread insert is broken, it can be checked step by step.
