Oil filter mounting nut/stud/bolt

There are a few different versions of those...

The worst one is the one with not enough depth on the hex and the sockets keep slipping off, if you get this style, get the one with the wider hex...

Or the one that uses an internal 3/8" square drive is also another good one...

Just don't get the one with the short hex... :icon_fU: :BangHead:
