M2 m4 m6 m8 Stainless steel self cutting threaded inserts with 3 borings
Stainless steel self cutting threaded inserts with 3 borings
Self tapping inserts is a kind of fastener with internal and external thread and cutting hole or groove. There are two kinds of materials: carbon steel and stainless steel. The surface of carbon steel is galvanized (yellow zinc, color zinc and blue zinc), and stainless steel is the natural color of metal.
Feature:
- Provide robust internal thread on soft substrate to meet the needs of multiple maintenance and disassembly;
- It can effectively repair the damaged internal thread;
- The self tapping sleeve is used after die casting, injection molding and other manufacturing processes, so the product structure can be simplified and the output can be increased;
- The self tapping sleeve can bear high load, so smaller inserts can be used to make the structural design of the product more compact.

302 type is the most widely used in all self tapping screw sleeve products. Its two slots not only play the role of cutting, but also have a little inward locking force.
Model 303 is a thin-walled version of 302 series, which is mainly used in some plastic or light alloy that cannot have thick wall.
For difficult to cut materials, it has larger wall thickness, shallower but sharper external thread. The screw sleeve uses three round holes as cutting edge. The difference between 307 and 308 is the length of the insert.

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
Manual installation:
Use the special screw sleeve installation tool. Refer to the figure below for the specific operation method. The end of the tool in the figure is a quadrangle head, which can be connected with a manual tapping wrench
Electric installation:
The DiI type of HRT numerical control suspension screw sleeve electric installation machine designed by AVIC can complete the installation of screw sleeve with high efficiency and high quality.
Installation precautions:
- It is necessary to select the appropriate drilling size according to different matrix materials;
- If the hole is large, it is easy to take out the screw sleeve when the mounting rod exits;
- If the hole is small, the installation of the screw sleeve will be difficult or even hindered.
- At the beginning of installation, it is necessary to ensure the perpendicularity between the screw sleeve and the base surface of the installation hole, otherwise it is easy to deviate and cause unsuccessful installation.
