302 Self Tapping Inserts m8 m10 m12 Slotted Threaded Inserts
Introduction

Self-tapping thread inserts are also called self-tapping thread inserts. They are a new type of fastener that enhances the thread strength. Self-tapping thread inserts have tooth patterns on the inside and outside. They are embedded in softer materials such as plastic, aluminum alloy cast iron, and copper, which can form relatively High-strength internal threaded holes, self-tapping thread inserts can also repair damaged internal threads.Self-tapping thread inserts are now widely used in the automotive industry, rail car industry, shipbuilding industry, household appliances, construction machinery, office machinery, electronic products, engineering plastics, high-end modular furniture, aluminum die-casting and other industries.
Use
Self-tapping threaded inserts are self-tapping threaded inserts with slots or holes. Slotted threaded threaded inserts are recommended for most applications. On some materials, this thread inserts 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 material cutting. This product not only has a very 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
Material

The materials used in domestic self-tapping thread insert are generally carbon steel and stainless steel.
1. Carbon steel: Color-plated zinc, suitable for surface carburizing heat treatment on aluminum alloy, copper alloy, plastic and other substrates with low engineering strength.
2. Stainless steel SUS303 (304, 316, 316L): suitable for surface passivation treatment on cast iron and other products with higher strength.

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 installation.
