Threaded inserts, also known as threaded sleeves or threaded inserts, are metal parts pre-embedded into pre-drilled holes in plastic or other non-metallic materials (such as rubber, wood, etc.).
The main function of these inserts is to provide a matching internal metal thread that mates with screws or other fasteners with external threads. Threaded inserts ensure a strong and sealed connection, compensating for the shortcomings of plastics or other non-metallic materials in terms of thread strength, wear resistance, and corrosion resistance.
With advancements in technology and the continuous emergence of new materials, the design and manufacturing processes of threaded inserts are constantly being improved and perfected, and they have a wider range of applications in the future.
