No with the info given, bit confused with the question, no mention of what you are actually planning to do.

A 68mm (threaded) shell would fit either an internal i.e. square taper/ISIS/Octalink, or External i.e. HT2/GXP/MegaExo.

BB30's are pressfit, and require the frame to have the shell designed for this.

The frame determines the BB type, which determines the crank type (this should match or be compatible with adapters)

Have a look here for mode info, Park Tool Co. » ParkTool Blog » Bottom Bracket Standards

More info about what you are planning to use would really help with a question like this.
