Actually, it isn't so much that you want to cut the NSSP links, it's
that you'd want to be able to control the "chip select". You can hang
multiple devices off a bus like NSSP as long as each device has it's
own chip select (and all participants aren't driving the bus when
they're not selected).

A 0-80 screw has a major diameter (where the crests of the threads
would be if they weren't rounded off) of 0.060" which is 1.524mm, so a
1.5mm metric screw should fit (since it's a teeny bit smaller).
