Matco Tools Symbol??

On the commute home I followed a Matco Tools truck. I was wondering what the symbol they use means. There is a six sided bolt. Inside it looks like the outline of an eagle's head to me.Any one know what it is? You can see it at their website below.

I believe the eagle's head is a crescent wrench, probably no meaning, just a catchy looking emblem.
