What size are the threads ? I'm looking for M8:1 at the top and M10:1 at the tip

These are 11/32 fine thread. You need metric course thread.

This looks like the thermocouple i just took out of my lennox hearth products shoreline model srh 40 but it is not listed on your compatablity list?

It should be a good replacement.

Will this work on a superior ssdvr-3530cnm?

Yes, this is the thermocouple for that unit.
