So I ran a stone around all the edges to reduce the potential of laceration and tried them for fit. You ain't gonna find anything that fits better. I tried them on three nuts and three top bearing caps and the wrenches fit just great. The opposite end on each is a std hex and just as nice. If you need these things this guy would be a good source to consider.
JMO of course
