The problem isn't usually with the screws themselves loosening. It's almost always because the stranded copper wire deforms and is no longer held tightly. This can happen not only with the Rockwell parts, but with the 40-amp fuse block as well.
Make tightening the electrical connections part of your standard preventive maintenance and pre-match checks, just like keeping proper chain tension or making sure the pneumatic release valve is closed.
