Like the best spokes, these water bottle cage bolts have precision cut threads.  They are designed to fit most bikes and water bottle cages.  They are made from 3-2.5 aerospace grade Titanium selected from the manufacturer's prime production run.

If you want to do something really cool for your bike, remove your standard bottle cage bolts and replace them with these Titanium bolts.

Each bolt weighs only 1.96 grams!

Yes... for a bolt, they are a bit on the expensive side.  But for that favorite bike of yours, it's definitely worth it.
