We've been using ENIG finish for our PCB's and installing tin plated hardware (self clinching, broaching nuts and standoffs)

We use anywhere from 1 or 2 pieces, to maybe a dozen, of this hardware on various assemblies.
These items are used just to hold or mount some items in place (no serious stress on these items).

Our mfg/assy facility in EU is balking at the finish mismatch and suggesting we change the board finish to immersion tin (which we've never used).

We've built all these assemblies, many, many times without issue.

Is there any other merits I should consider, before I tell them please build them as is?
