Has anyone used threaded inserts instead of trying to thread MDF. I thought about just using epoxy and regular nuts. Think JRGO pipe adjustment blocks. Any luck?

I just drill the hole to tapping size, squirt a bunch of super glue in the hole, let it set, and then tap.

Try these: McMaster-Carr

If you need the back side of the t-nut to be flush with the surface of the board, you can use a spade or forsner bit. These are great and I use them all of the time.

Look up 'dowel nut' on mcmaster also.
That might fit the bill, depending on what you are trying to do.

I've used the threaded inserts as well as t-nuts. I'm not a fan of either. My experience with the threaded inserts is that they distort the MDF when you screw them in and then can still start turning. I also broke some. I ended up epoxying in the ones I was using after I had them installed. This worked, but it was a pain. The best setup I've ever used for threads in MDF was cutting pockets for regular hex nuts to lightly press into and then epoxying those in.

I think the dowel nuts are the easiest method. An alternative would be to epoxy coupling nuts into the MDF.
