M4 Self - Tapping Thread Insert With Hole On One Side M5 For Plastic
Introduce
Self-tapping threaded sleeves are also called self-tapping threaded sleeves. They are a new type of fastener that enhances 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.
Use
The self-tapping screw sleeve 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 function. If it still does not work, it is generally recommended to use the 307/308 type, which has made a major breakthrough in the difficulty of cutting materials. 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 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.

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.
