Self-tapping screw is a new type of fastener with enhanced thread strength. The self-tapping screw sleeve has tooth patterns inside and outside. It is embedded in soft materials such as plastic, aluminum alloy cast iron, and copper, which can form relatively High-strength internal thread holes, self-tapping screw sleeves (self-tapping sockets) can also repair damaged internal threads.
A self-tapping threaded insert is a self-tapping threaded insert with a slot or hole, of which the slotted self-tapping insert is recommended for most applications. On some materials, this insert provides a perfect specific thread locking effect. 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 force requirements or special design. , The application of self-tapping screw sleeves runs through almost the entire metal and plastic processing industry, and the products have long been used in the automotive industry, civil and commercial vehicle engines, transmissions, aviation industry, rail car industry, etc.
