You're going to find that the ratcheting box ends will be too big to get into a lot of the spots we work on around a stovebolt engine compartment. They're handy for spinning bolts and nuts down as long as there's plenty of room around the bolt head. I had a set of ratcheting box ends in sizes from something like 3/8" to 3/4", but a former employee liked them so well they followed him home when he changed jobs, along with a bunch of other tools.
