I used these legs on my Ikea Kallax. I didn't like the color but I liked the price and they were solid wood so I sanded them down and coated them with Danish walnut oil. Instead of screwing them in I drilled a hole where the leg threads go and laid the panels on the floor as the Callax is hollow inside. I would recommend laying a piece of plywood on the bottom to drill through and then laying the callax on top.
