80 pieces threaded helical inserts in SS304 stainless steel, wire spool M3 to M14

Discover our stainless steel threaded inserts, the ideal solution for reinforcing and protecting your bolted assemblies. Designed for use in low-strength materials such as aluminum or magnesium, these inserts prevent thread damage and ensure excellent connection performance. They significantly improve the strength and reliability of your fasteners. Perfect for parts requiring frequent assembly and disassembly, they greatly extend the service life and wear resistance of threads. Thanks to their elasticity, they evenly distribute the load on each thread, eliminate pitch and tooth misalignment between the screw and the tapped hole, and absorb vibrations. This increases fatigue resistance and the overall strength of the assembly. They also prevent screws from loosening, which is essential for applications requiring a high safety factor. Their maintenance is simple: insert an insert into a damaged screw hole to immediately restore it to service, thus avoiding the loss or costly replacement of parts.
