self-tapping thread inserts, also called self-tapping thread inserts, are fasteners with internal and external threads and cutting holes or cutting grooves developed by Dalian Andy Machinery Equipment Co., Ltd. The accuracy level of external threads is generally, and the accuracy level of internal threads is Generally, after installation, the thread strength of the bottom hole is higher and the effect is better. Its surface hardness can reach up to. It has the characteristics of self-tapping, and there is no need to use a tap to process the thread of the bottom hole (the workpiece can also be pre-made with threads for quick installation as needed). It only needs to pre-drill the bottom hole and then install it directly with the installation tool. It has high installation efficiency and is easy to use. It can significantly improve the connection strength and wear resistance of workpieces and effectively simplify product design. Self-tapping thread inserts are used on light alloys (aluminum, magnesium, zinc and other alloys), cast iron, brass, bronze, thermosetting plastics, laminates, hardwood and other materials. At the same time, self-tapping thread inserts can also be used to repair damaged internal threads. After repairing and installing R self-tapping thread inserts, the original bolts can still be used, which is economical, beautiful, convenient and fast. R self-tapping thread inserts are now widely used in the automotive industry, subway systems, military supplies, home appliances, and construction in many advanced countries. Machinery, business machinery, electronic products, engineering plastics, high-end modular furniture, aluminum alloy castings and other industries.
