Perfect 3M inserts for plastic or wood.
These were the perfect M3 threaded inserts for the printed parts I made for my 3D printer, Over time threads in Plastic will fail. I don't see these ever failing from use.

Great inserts. Smooth threads.
M4 seems to be my go to size when I'm using threaded inserts. This pack was a great replacement for the lack of M4s on my workbench. I used them to finish a recent project of attaching a foot to a base for my leg lamp. It worked wonderfully and the price per piece was a nice value. Easy to install and very smooth threads.

Seems good enough
I haven't used any yet, so I'm not sure as what to expect. Good amount of different sizes which was what I was looking for anyway.
