How To Prevent Self-Tapping Screws From Hardening And Bending

For people who often use self-tapping screws, self-tapping screws must undergo a hardening heat treatment process to improve their hardness. However, sometimes self-tapping screws will bend during the hardening process. So, how to prevent self-tapping screws after hardening bending? As a professional fastener manufacturer, Xinchi is happy to share with you the method to avoid bending after hardening of self-tapping screws.

In the production process of self-tapping screws, the hardness of the screw itself may not be enough to meet customer requirements, so it needs to be hardened. However, during the hardening process, some self-tapping screws may bend, especially long screws. To avoid screw damage, we need to pay attention to the following points:

Palletizing problems during heating treatment: the range of long screws is large, and uneven palletizing may lead to bending of screws. In addition to palletizing problems, other factors can affect the bending of screws.

Control the rate of temperature rise: Rapid temperature rise may cause the screw to bend. Ensure proper heat treatment temperature.

Temperature control and heat treatment temperature: Too high heat treatment temperature can also cause screw deformation. In the heat treatment process, it is imperative to know the raw material’s critical point and temperature control.

Therefore, whether it is the manufacturer or the customer, in the hardening heat treatment process of self-tapping screws, attention should be paid to the above aspects to avoid the occurrence of equipment defects or screw damage. Through the correct treatment and precautions, you can prevent the bending of self-tapping screws in the hardening process.
