Just saw this in a banner add. Might be kind of cool when using weak materials like MDF to get a stronger thread.

Interesting, but you don't then have a flat surface to mount the drive unit to. I just use a bit of epoxy on the back of the nut (after degreasing it with IPA) prior to hammering it down.
I saw that. Simple recess will do. I too have used a flexible epoxy, like West. I keep trying to come up with a simple de-coupled mount, something like Well-nuts but there is just not the space.
Threaded inserts are OK and I've used them on some projects. They are useful if your hole is close to the edge of the cutout. The headless ones allow you to fit after making the cutout, which can be useful in some cases.
T-nuts seem to be made of stronger material (less chance of thread stripping) and the flange and rear mounting make sure it won't pull out.

With smaller drivers, you don't have enough "meat" around the holes. T-nuts need a smaller hole than a threaded insert. Those cheap Silver Flute mid-woofers I am playing with are an example. With thick baffles and the desire to bevel the back side a bit, you run out of material. I am experimenting with how MDF absorbs poly resin or varnish to see if one could actually plasticize enough of the edge and drill/tap it. On some big honking 12 inch sub, it is a totally different story. This tool just looked like an interesting bit of kit.
Yes, I forgot that some people like smaller drivers. I only use them on woofers, screws for smaller drivers.
I have always installed t-nuts using the same technique but with a less dedicated tool made out of a washer and a bolt. The bolts tend to strip, be interesting to know how long this tool would last.
