The self-tapping thread insert is a new type of special fastener for strengthening the strength of the thread. It has internal and external teeth as a whole and can be embedded in relatively soft materials such as plastic, aluminum alloy, cast iron, and copper to form an internal threaded hole with higher strength.
It has the following characteristics and advantages:
No need to pre-tap the thread: It can be directly screwed into the specific hole reserved in the base material.For the damaged female thread, the same original screw can also be used, which is both economical and beautiful.For new products, it can also increase the strength of the thread.
Repair the internal thread: It can repair the damaged internal thread.
Wide application: It has been widely used in industries such as the automotive industry, rail vehicle industry, shipbuilding industry, home appliances, construction machinery, office machines, electronic products, engineering plastics, and advanced modular furniture.
