Some customers may ask, why is it prone to slippage in the countersunk torx screws he purchased? I will analyze the reasons for everyone today.

1. The insertion depth is not enough, or the groove is too shallow. It may be that the punch in the production of the countersunk internal Torx screw is not very good, and the internal Torx of the screw is not very symmetrical, or the Torx during the production process The size does not comply with the regulations and is generally too large. There is also a case of the plum blossom punch that the corners of the plum blossom in the countersunk head are blurred, etc., which causes the depth of the punch thimble to be insufficient.

2. It is possible that this countersunk head internal Torx screw has some minor problems during production, which will cause the internal Torx slot to be slightly too large. After a period of use, the European standard screw punch will cause slippage after friction. The phenomenon of silk.

3. The hardness of the Torx screw in the countersunk head is low, and the Torx is easily deformed when being loaded and unloaded many times, resulting in slippage. If this is the problem, the manufacturer can increase the hardness of the plum blossoms in the countersunk head by changing the heating hardness.
