Sorry but I am not wrong. The bedrug will compress until it is a solid flat surface between the tiedown and clamp. That's like saying any bolts with a washer won't keep torque either. And it's not the same thing as putting 2 washers between the tiedown and bed wall, because that would leave a gap between/around the back of the tiedown and room for a moment arm to torque/twist. The bedrug behind the tiedown is equivalent to a solid shim and there is no open gap for a moment arm torque around the bolts when its bolted securly and the bedrug is fully compressed. We're not talking about a 6" thick piece of squishy foam, or even 1" thick piece of squishy foam where you can't fully compress it. The tiedowns will never come loose even bolted on top of a bedrug.Besides the engineering side of it, nearly 10 years of a bedrug installed on my truck with the tiedowns bolted on top of the rug, they've NEVER come loose. And I use them all the time, and put them to some strenuous work. You can come over and put a torque wrench on the bolts as well if you'd like, I'd bet my title on it that they aren't loose
