RE: Extreme Low Temp. Bolts
For this temperature range, austenitic stainless steel fasteners typically are specified according to ASTM A320. There are several grades to choose from, depending on the desired strength and corrosion resistance. Take a look at the following link for some basic information:

RE: Extreme Low Temp. Bolts
All of the B8-type fasteners are suitable for use down to -300 F. Because these are austenitic stainless steels, they are not really susceptible to a ductile to brittle transition like ferritic or martensitic steels are. These fasteners are lower strength than L7, but they definitely can be used for your temperature range.
