The earlier HF tool did not have alignment pins (the later ones do have

blade from turning.


This is the one I have and I never have a problem with the blades
loosening it they are centered properly. There is a small ring
protrusion on the tool that goes around the bolt and inside the blade
hole, which perfectly matches the hole in the blades. It is an exact fit
and it's easy to tighten the bolt without the blade being around this
ring. It will never tighten enough if the blade isn't sitting flush
against the tool, around this ring.
