How does it differ from a carriage bolt?

I'm looking (so far without success) for a type of bolt that:
1.  slight convex head
2.  underside of head has 4 facets (sides) that taper inward.
The bolt is designed to fit into a small casting with a matching 4-sided
tapered hole to lock bolt from rotating while being tightened.

Anyone ever seen anything like this?
