Review on 🪜 SINGTAN Furniture Levelers with Screw-in Nuts - 8 Pack, Heavy Duty Adjustable Feet 1-inch Legs, Table and Chair Levelers, 3/8''-16 Threaded Bolt, Thread Pitch: 16 by Mark Green

read where some people had problems with them breaking during installation. The largest diameter of the solid part of the nut, excluding the thread itself, is 0.5". If you are drilling a hole less than 1/2 inch, the hard part of the nut needs to compress the wood as it is screwed in. This is a difficult task, especially when trying to install in hardwood. If you use a 1/2" drill bit, only the thread will cut into the wood the way it should. It's a good thing I have more tools than Home Depot because the package didn't come with the right size Allen wrench to install them. With. I guess I'll have to get it from the tool box. heaven for protection. It was always possible to tighten the nut with a 3/8x16x3/4 bolt instead of a hex wrench. I was under the mistaken impression that the legs were made of a softer material. They are closer to plastic than rubber in hardness. Otherwise a good product that works as advertised.
