Use OF

The self-tapping screw is a self-tapping threaded insert with a slotted or open hole, and the slotted self-tapping screw is recommended for most applications. 

In some materials, this threaded sleeve provides the perfect specific thread lock function. If it is not enough, it is generally recommended to use the 307/308 type, and the 307/308 type has made a major breakthrough in material cutting difficulties. 

This product not only has a thick wall but also has three circular holes with cutting ability scattered on the wall. The 307/308 product is especially suitable for materials with a small thickness.

 Generally, there is no need to install a self-tapping screw sleeve, but some important joints need to be installed because of high tensile force or special design. 

The self-tapping screw sleeve is manufactured and tested strictly according to the ISO/TS16949 quality system. The self-tapping screw sleeve application is used throughout the metal and plastic processing industry.
