Slotted Self tapping thread insert for mental

The 302 series is the most widely used of all self-tapping thread inserts, with two slots that not only cut, but also provide a slight inward locking force.

The 303 series is a thinner walled version of the 302 series and is mainly used in plastics or light alloys where thick walls are not possible, and where lubrication may be considered for installation in special cases.

◆Provides strong female threads on soft substrates to accommodate multiple repairs and disassembly needs;
◆Can effectively repair damaged internal threads;
◆Self-tapping sleeves are used after die casting, injection molding, or other manufacturing processes, so they allow for simplified product mix and improved yields;
◆Self-tapping bushings can withstand high loads, so smaller inserts can be used, resulting in a more compact product design.

Manual Installation:
Use the special thread insert 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 Dill type of HRT numerical control suspension thread insert electric installation machine designed by AVIC can complete the installation of thread insert with high efficiency and high quality.

Attention during installation
1. For different processing materials, refer to the drilling size specification for pre-drilling processing. When the hardness of the corresponding material is high, please slightly increase the bottom hole within the drilling range.
2. With the slotted end of the socket down, install the self-tapping thread insert completely into the front of the tool, and it should be in vertical contact with the work piece. When installing (1 to 2 pitches), please make sure that the bottom hole is aligned and never tilt. If tilting is detected, do not reverse the tool and readjust before using. After 1/3 to 1/2 of the way in, do not start again. In addition, please do not reverse the rotation of the tool, otherwise it will cause product failure.
3. The self-tapping thread insert should be at least 1mm below the surface of the part after assembly.

One of the most significant advantages of the self-tapping thread insert is its ability to repair damaged threads or loose connections. It easily corrects damage to existing threads and provides a new, secure base for a stronger connection. This solution not only saves time, but also improves the overall reliability of the workpiece.

Self-tapping thread insert are used in a wide range of applications across multiple industries. They are used in automotive, aerospace, machining and electronics. They are used to repair damaged threaded holes, enhance the robustness of connections, and maintain stable connections under high pressure, high vibration, and extreme temperature conditions.

Generally there is no need to install the self-tapping thread insert for products that do not require it, but some important connection parts need to be installed due to high tension requirements or special design. Self-tapping screws are strictly according to the ISO/TS16949 quality system to produce and test products, self-tapping thread insert are used throughout almost the entire metal and plastics processing industry, the products have been used for a long time in the automotive industry, civil and commercial vehicle engines, transmissions, aerospace industry, railcar industry and so on, and its quality has never been questioned.
