The HNS0080 should work with the wrench you already have.
If you get the small pattern nuts you'll have to call microfasteners to see if they have a wrench for it.

Well, the threads are the same for both. In that regard, either will work just fine with a 0-80 screw.

The first nut linked is a small pattern nut, if you're using the microfastener wrench for the nuts it wont work with the small pattern nut.
