I'm looking for a compact and inexpensive way to attach a threaded part parallel to the surface of a sheet metal part.
One "easy" way to do this, in my mind, is to use a threaded block similar to an alternator spacer block, seen below, but I can't find this kind of part on McMaster.com. I'm not sure if that's because this is an obscure part or if I'm not calling it by its proper name.
When I searched "Alternator adjustment block" on Google images the pictures above showed up, and both of those images are called, "alternator adjustment spacer block," but searching that term doesn't seem to pull up too many more results.
Ideally the block I'm looking for would have three holes, as in my drawing below. See also the drawing of the desired setup.
Again, to be clear, I'm looking for the name of this part as I'm not sure what the specific name of it is, if it has one. With the name I can then find parts sources myself (not a shopping request).
