How are thread inserts measured?
Modern threaded plastic inserts are stipulated by a measurement of the outer diameter (OD), which is measured over the pipe thread in the case of a male pipe.

Are threaded inserts better than screws?
They offer a stronger alternative to weld nuts and tapped holes, and they provide a stronger bond than self-tapping screws. In fact, threaded inserts are usually the strongest and least time-consuming fasteners used in any manufacturing setting, especially because they were designed for automation.
