Review on 🔩 Swpeet 122Pcs Carbon Steel Color Zinc Plated Carbon Furniture Screw in Nut Threaded Wood Inserts Bolt Fastener Connector Hex Socket: 1/4 + 5/16 Assortment Kit by Rudy Santos

This is fantastic. I saw some bad reviews and checked the quality immediately after purchase. With a proper lead overall they were a perfect match for a hammer drill and hex head. I've tried inserting a 1/4" x 3" bit and pulling it out in a vise but to no avail. I then used them to build a kids loft bed and they worked great, very strong. The only complaint I have is that the internal threads are a little loose, but that doesn't take away from the fact that they feel incredibly strong.
