Anyway, a great thread today confirmed, in addition to what ElwoodBlues posted, there's yet another type of mechanical tensioner that looks different than the ones pictured prior.

Since the identification of the type of tensioners is visual, I'll repost the picture here from a 2003 BMW 525i.

Notice the lack of the raised molded nut. Instead there's a sunken Torx #60 indentation. Who knew!

For record purposes, the picture shows the lower (AC) belt tensioner (new and original). Part #11287512758. According to it is for vehicles manufactured "from 9/2002" that have a mechanical tensioner. This is NOT the upper accessory belt tensioner.
