If you are uncomfortable with epoxying a magnet to a drain plug get the ones that are drilled/countersunk and attach it mechanically as well.
That occurred to me, but as I'm doing a gearbox and OD rebuild and it's my quest to build the only non-leaker--with synthetic oil--Healey gearbox I don't want to add another potential leak. I also thought that, as powerful as they (likely) are, you could just put one inside a gearbox/diff plug--the hollow ones--and the field would probably do the job nicely, even through the plug. But, if they are that powerful, you couldn't pry one out to get a 'socket' in (I use a ground down 3/8"->1/2" adapter; hmmm ... I'm gonna measure the depth of these). Confession: I bought a couple just to play with. Well, I will use them to fish any iron out when I cut open a filter.
