A few months back I looked into quality bolt manufactures. The one that seemed good has the letters THE in raised print on the head of the bolt. Get the THE bolt in 316 SS. THE is a Tawain bolt manufacturing company that looks to make quality bolts and nuts- they look to be the largest in the world.
I would question rounding off the head of a bolt. The bolt head might be forge and rounding would severly lower the bolts strength. Also, the bolt now needs to be polished and passivated.
