Anwenk 40Pcs 1/4"-20 x 20mm Furniture Screw in Nut Threaded Wood Inserts Bolt Fastener Connector Hex Socket Drive for Wood Furniture Assortment (with Hex Spanner)

good

I purchased these for the price, which is like a tenth of what I'd spend at my local hardware store or a big box store. I suspected I'd get a few duds with defective internal threads but that was not the case — I tested each of the 40 pieces in my set and the internal threads all worked fine with a 1/4-20 threaded foot. That's not to say YOU won't get some duds, just that I did not. I'm also super happy with this mfr's range of available sizes — I felt as if I had some good choice in customizing the insert size to the threaded feet I was using, as well as how far into my project's legs I wanted to go. As far as installing them, I cannot speak to hardwoods right now, but in the soft wood I was using, they were completely painless. I stepped up my drill bit sizes one by one, slowly, always checking level in two directions (I was unable to fit my particular project into a drill press), and I installed them into the legs also very slowly, and also always checking level in two directions. I definitely recommend this product and I will almost certainly buy again.

Good product

Excellent quality

I make wooden knobs for many different projects and I prefer to attach the bolt to the knob in many cases. These are great because they can go into a piece and wont just pull out if stress is put on them like with some tee nuts. They leave the piece with a clean look and I feel like I can depend on them since they are threaded in.
