Please help ID a titanium bolt
 

G'Day,

I picked up a bolt from the scrap dealer which I'm sure is some form of
titanium alloy...(due to it's weight, corrosion resistance, non-magnetic
and sparks)
The head of the bolt is stamped UT and T I 2... can someone please
tell me what the composition is, and is there particular speeds, or
tools I should use to turn it?
FWIW, I'm planning on making some piercing units, injectors, etc out of
the stock, but I need to know what it is first.

Thanks,
Des
