There isn't much better surface for gluing something than threads.
I probably will use JB Weld for attaching a nut to the spindle of Milwaukee's cordless mud mixer, for my next electric bike. The glue being necessary because the drill will run in reverse, on the left side of the bottom bracket. I will correct this if it doesn't work. I used JB Weld once before, but the lesser drill burned up, so it was a short test.
