Review on PGMJ 80 Pieces M6 Wood Inserts Bolt Furniture Screw In Nut Threaded Fastener Connector Hex Socket Drive For Wood Furniture Assortment (M6X20Mm) by Leo Govindan

I used these to make my closet organizer and they are way better than regular glue/nails or screws when working with chipboard. In addition, it can be disassembled if necessary. The only small problem is that you have to either make a centering jig for the rim holes or use a dowel jig to drill properly. As such I would happily use them for many of my furniture projects and highly recommend them. Very nicely designed and high quality item!
