odd oil pan bolt
 

Been meaning to ask about this sooner, but recently noticed on the bottom of the oil pan what appears to be a small, slightly angled bolt (may 6 - 8mm? in size). Initially, it looked like somebody screwed up installing it, but on second glance appears to be cast as part of the oil pan. Been trying to find an online picture of one, but can't find one yet. I can photograph this eventually if it doesn't ring any bells. Anybody have any info on this?

Thanks!
Greg
