I need a bolt that can stick out the other side of the surface it is threaded into. The exposed portion of the bolt should be smooth, so as to be used as a bearing surface for a transverse load.

If a short turned diameter with a flat point is what you want it is called a dog point screw. Another would be a rounded point screw that has a radius on the end. A flat point (oxymoron) is a flat, small chamfered point.
Dog point is usually better due to the end mushrooming when pressure is applied, making it hard to remove the screw. This will not happen with a dog point because there is thread relief on the end.
First link is to a fastener house that shows many different types of screw points. Second link is to McMaster-Carr a good industrial supply house.

Never seen one of those (not in inch sizes either). Doesn't mean they don't exist, though. If you have the equipment, your best bet will probably to just chuck up your screws on a lathe and then turn down the end to your desired dimension.
Or you can try this: thread the screw thru your peice, and then thread a round spacer onto the exposed threads. Search for metric threaded spacers or standoffs on the web. One site that came up for me was: http://www.keyelco.com/products/metric-threadedstandoffs.asp
finally, you can just use the threaded end to transmit the load if its light enough.

A setscrew would do that. You can get one with a flat end or one with a nylon tip sticking out of the flat end that would make an even-better bearing surface.

Check out Fastenalls website, I'm sure they will have something you can use.
