Special thread sleeve for mold

It is a fastener with internal and external threads and cutting
holes or cutting grooves developed by Dalian Andy Machinery Equipment Co., Ltd. The accuracy level of the external thread is generally , and the accuracy level of the internal thread is generally . After installation, the bottom hole thread Higher intensity

and better effect. Its surface hardness can reach up to. With self-tapping characteristics, there is no need to use a tap to process the threads of the bottom hole (the workpiece can also be pre-threaded for quick installation if required). It only needs to pre-drill the bottom hole and then install it directly with the installation tool, which improves installation efficiency. High and easy to use.

It can significantly improve the connection strength and wear resistance of workpieces and effectively simplify product design. Self-tapping screw inserts are used on light alloys (aluminum, magnesium, zinc and

other alloys), cast iron, brass, bronze, thermosetting plastic laminates, hardwood and other materials. At the same time, self-tapping screw inserts can also be used on damaged

Internal threads are repaired. After 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 many advanced countries. Used in the automotive industry, subway systems, military supplies, home appliances, construction machinery

, office machinery, electronic products, engineering plastics, high-end modular furniture, aluminum alloy castings and other industries.
