Made from zinc-plated carbon steel, these are pretty sturdy! These are our standard tee nuts. They're cheap, they solid, and they do the job well. These feature an M5 thread, making them compatible with the low-profile M5 screws we carry.
We also have a few other varieties of tee nuts that can be useful in different situations - check the related items.
