28 Bolt Feature?

Recommended Posts

I noticed that all of the 28 bolts I have seen have a hole about .1 dia. on top of the bolt "nose" about 5/16 from the end of the bolt.


Does this hole have a purpose?


Was it needed only for alignment during manufacturing?


Has anyone observed a bolt without this hole?
