Review on PGMJ 80 Pieces M8 Wood Inserts Bolt Furniture Screw In Nut Threaded Fastener Connector Hex Socket Drive For Wood Furniture Assortment (M8X25Mm) by Matt Conner

The supplied drill bit is too big and has been bent so that the hole is larger than the thread so that nothing can be cut into it. Using the same drill bit from my set that is right now is still too big. I had to reduce it 2 sizes so it was tight enough not to loosen just when turning the bolt. I'm glad I tested it first, but you'll most likely need a different drill. The price was right and they work well once sorted out
