SUS303 Self - Tapping Wire Thread Insert M2 M3 M4 3/4 For Wood Insert
Use
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 generous.
Generally, there is no need to install self-tapping screw sleeves for products that are not required, but 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. Industry, rail car industry, etc., its quality has never been questioned.

Introduction
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.

Installation Precautions
1. For different processing materials, refer to the drilling size specifications for pre-drilling processing. When the hardness of the corresponding material is relatively high, please slightly increase the bottom hole in the drilling range.
2. The slotted end of the screw sleeve is downward, and the self-tapping screw sleeve is completely installed into the front end of the tool, and it must be in vertical contact with the work piece. When installing (1～2 pitch), please make sure to align the bottom hole and never tilt. When you find that it is tilted, please do not reverse the tool and readjust it before using it. After entering 1/3~1/2, you cannot start again. In addition, please do not rotate the tool in the opposite direction, otherwise it will cause the product to malfunction.
3. The self-tapping screw set should be at least 1mm lower than the surface of the part after being fitted.
