Stainless Steel 302 Self Tapping Threaded Inserts for Soft Metals
Information
Self-tapping threaded sleeves are also called self-tapping threaded sleeves. They are a new type of fastener that enhances the thread strength. Self-tapping threaded sleeves have tooth patterns on the inside and outside. They are embedded in softer materials such as plastic, aluminum alloy cast iron, and copper to form a relatively High-strength internal threaded holes, self-tapping screw sleeves (self-tapping braces) can also repair damaged internal threads.
Self-tapping threaded sleeve mounted without prior tapping, installation tool can be used directly screwed into specific holes in the base material reserved for the female thread teeth have been crushed and the original can be used the same screw, economic appearance, the new articles It can also increase the thread strength. Self-tapping screw sets (self-tapping braces) are now widely used in the automotive industry, rail car industry, shipbuilding industry, household appliances, construction machinery, office machinery, electronic products, engineering plastics, high-end modular furniture, aluminum die-casting and other industries.

Installation method
Self-tapping screw sleeve installation method
1: When the number of installations is small, a simple installation method can be adopted. Specifically, the method of corresponding specification bolt + nut is adopted, and the self-tapping screw sleeve is fixed on the bolt of the corresponding model, and the nut of the same model is used Fix it to make the three into a whole, then use a wrench to screw the screw sleeve into the bottom hole, and then pull out the bolt.
2: When the number of installations is large, special self-tapping screw sleeve installation tools can be used, first install the self-tapping screw sleeve on the special tool, and screw the installed screw sleeve into the pre-made hole about a circle , After ensuring that the tool is perpendicular to the end face of the prefabricated hole, screw in the screw sleeve forcefully. When the end face of the self-tapping screw sleeve is about 0.2mm lower than the end face of the prefabricated hole, stop screwing in and screw out the special tool in the reverse direction. The end of the self-tapping screw sleeve installation tool is a hexagon head, which can be connected with a manual tapping wrench, or an electric or pneumatic tool.
Application
It is widely used in aerospace components, locomotive, high-voltage electrical appliances, automotive power, wind power, nuclear power, communication and electrical industries. It is used in aluminum, magnesium, copper alloy, plastic, plexiglass, plywood, steel, cast steel and cast iron to make it more tough and firm.
