I didn't trust threads into aluminum for multiple assembly/disassembly so there is a steel nut that is epoxied inside the aluminum box.

I would hope that I don't have to worry about anything bending. The bike boxes can only weigh 50 lbs max to avoid airlines exhorbitant overweight fees. So the heavy end of the box might be 35 pounds spread over two wheels is unlikely to bend anything. I'll keep the roller blade wheels in mind if these are found lacking. I must of hit about 10 thrift stores and only found zero roller blades and only one skateboard with bad wheel bearings.

That would also mess with thee adjustability. This is designed for bike box width of 8"-12".
