I like the bolts, but maybe remove the outer ring so it is just the hexagon shape in the metal. I like the bolts in the position of the satrs in #120, rather than diagonally.
What I meant by about the outer ring thickness, is that maybe if the new ring (that contains the words) is over the original outer ring, that would improve the thickness of the new emblem. As of now, there is the original ring, plus the thickness of the new ring, so it is double thick.
Hope this makes sense.
