What's the size of the bolt that fits the 049's prop and aluminum spinner? I don't want the stock slotted head screw. And I recall I had one where the socket Head of the screw was flush with the top of the aluminum spinner, in other words the spinner was drilled out on the top deep enough to cover the head of the bolt. Who has them, or who makes them? Thanks. P.S. I modified this post to remove the word HEX. What I meant was the socket type head, typically like the ones we use for our larger engine
mounting bolts. Kevin.
