Preventing Self-Drilling Screws from Slipping During Use
There are many ways to prevent screw slippage. You can choose the best method based on your specific situation. The main methods are as follows:
1. If the problem is with the screw’s material, you can purchase higher-quality screw wire to manufacture the screw. The hardness of the screw wire determines the hardness of the screw. Of course, this is without hardening.
2. If the screw is used on hard materials such as iron plates, and the screw itself is not hard enough, you need to harden it. Hardening also has hardness requirements. Generally, 480-550 HV is sufficient.
3. For slipping screws, you can use methods to increase the strength grade. For example, internal hex bolts and external hex head bolts. Self-drilling screws come in grades 4.8, 8.8, 10.9, and 12.9. If you have a grade 4.8 screw, you can replace it with a grade 8.8, 10.9, or 12.9 screw. In short, replace the lower-grade screw with a higher-grade one.
4. If the threads are slipping, it is recommended to harden the screw and apply adhesive to the threads. This can help prevent loosening.
The self-drilling screw manufacturer, Hebei Wotu Fastener Manufacturing Co., Ltd., uses imported and domestic large-scale steel mill raw materials. Its production equipment is all from Taiwan, and it has a complete testing process and equipment. Operating under a modern enterprise system, it strictly manages according to the ISO9001:2015 quality system.
Fixed anchor bolts, also known as short anchor bolts, are cast in with the foundation and used to secure equipment that does not experience strong vibration or impact. 1.

A screw is a tool that uses the physical and mathematical principles of inclined planes, circular rotation, and friction to gradually tighten objects and machine parts. A self-drilling screw is a screw with a self-tapping drill bit at its tip. Screws are a common invention of humankind throughout history, and in terms of application, they […]
