💡 Why do threaded inserts provide better strength in plastics than regular nuts?

The screw threads bite into surrounding material for a locked connection.

- Knurl texture grips firmly without needing a welder or glue stick

- Steel core offers higher pull out resistance than brass alternatives

- Threads match common bolts for universal fitment across many tools
