Steel M5 M6 Side Slotted Brass Self - Tapping Thread Inserts With ISO Certification
Introduction
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 threaded sleeve braces also called self-tapping, is a new type of reinforcing the strength of the threaded fasteners, self-tapping threaded sleeve has inner and outer tooth pattern, embedded in plastic, cast iron, aluminum, copper and other soft material, can be formed relatively an internally threaded bore high-strength, self-tapping screw sets (self-tapping braces) may repair the internal thread has been bad.

Use
The self-tapping thread insert is a self-tapping threaded insert with a slot or hole. The slotted self-tapping screw sleeve is recommended for most applications. On some materials, this threaded sleeve provides the perfect specific thread lock effect. If it still does not work, it is generally recommended to use the 307/308 type. The 307/308 type has made a major breakthrough in the difficulty of material cutting. 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 the case where the material thickness is not too wide.
Generally, there is no need to install self-tapping thread insert for products that are not required. However, some important connection parts need to be installed due to high tensile requirements or special design. Self-tapping screw sleeves are produced and tested in strict accordance with the ISO/TS16949 quality system. The application of self-tapping screw sleeves almost runs through the entire metal and plastic processing industry. The products have been used in the automotive industry, civil and commercial vehicle engines, transmissions, and aviation for a long time. The quality of the industry, railcar industry, etc. has never been questioned.

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.
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 installatio
