The pool professional who closes our pool wants to drill 6 new holes in our concrete deck because 6 of our loop loc cover anchors are stuck. Three of them have bolts that are stripped. Two appear to have been tightened too tightly so they won't budge. One bolt just spins when you try to loosen it but the anchor won't come out of the concrete. He tried spraying them with penetrating oil and WD-40 and it didn't help. He spent almost an hour trying to remove the bolts from the concrete with the tools that he had on his truck and he couldn't get them out. A few weeks later, I sprayed them again with penetrating oil and WD-40 and tried to get them out with various tools that I had in the garage and I couldn't get them out either. We just used the cover with those 6 anchors unattached last winter without any issues, but we would like to get it fixed this year, if possible. Are there any tools that I could buy to get the anchors out so I wouldn't have to get 6 new holes drilled into the concrete deck? Does anyone sell an anchor removal kit that has all the tools you would need to remove stuck anchors and detailed instructions on how to do it? If nobody sells a kit like this, could someone give me a detailed tool list for what I would need to purchase to remove these stuck anchors?
