WMYCONGCONG64PCS Iron Plate Nut Screw Set 3/8” Brad Hole Tee T-nut with Round Base Furniture Hardware Flange Insert Female Thread T-Nut with Mounting Screws Set (3/8" - 64Pcs)

Has done a great job holding couch legs on

I've used threaded inserts in the past, but have cracked plenty of them when installing them. Home depot sells a similar item to this but it's so small and thin. These things are heavy and feel so much more durable than any other option. They're a little more involved to install if you want them to be flush, but it's a pretty simple process. My only complaint is that the countersunk holes are shallow enough that the provided screws don't sit flush like I needed. I used a countersink bit in my drill press and cut each hole deeper, not a huge deal but would've been nice if they had just fit in there nicely. Otherwise great product.

it's 64pcs total with the screws not the actual t nuts.

These are advertised (at least partially) as being 3/8-16. They are not. They are likely metric but will definitely not thread into anything 3/8-16This is blatant misrepresentation.

So i Had to waste a lot of my time in re tapping a new metric M10 thread into all of these. As M10 bolts wouldn't screw in to these as these fittings have a different thread pattern cut into them imperial not metric as described. But they work now.
