I'm putting together this TV cart thing, and the wheels that supposed to go on the bottom wont screw in all the way, on one side at least. One side I could screw them all the way down with the wrench that came with it, but on the other side I feel like I'm stripping the metal every time and theres a little less than an inch left before its impossible to keep twisting. So right now I have a lopsided tv cart and I'm not sure if I should just take it back.
