Got an interesting email from a guy. He's got a WWII prop hub he's trying to identify. The only markings he's found so far are on the bolt heads, the triangle and circle indicating the bolts are close tolerance/high strength bolts.
Here's the interesting bit: The markings are STAMPED into the head, rather than raised like most bolts (forged or molded, I guess).
The only thing that occurred to me was some sort of limited-production bolt that was custom-machined rather than mass-produced.
Anybody have any ideas?
