hardware for ss bolts
(OP)
We have a cut-off saw that has SS socket bolts with carbon steel t-nuts for the clamps and hold downs. The nuts are seizing due to the coolant. We replaced the bolts and nuts and added corrosion inhibitors to the coolant but my questions are, should we switch to SS nuts or will galling be a problem? Also, does Cu or Ni based anti-seize help this or help with the seizing of the carbon steel nuts? I'm a recent grad and haven't had any experience with this so I'm looking for some help. Thanks.

Before totally changing fastener materials, I would try the anti-seize, and don't be stingy with it.
Cheap fixes first.

In general, nickel is likely to be stronger and more corrosion resistant, but more expensive also.

In our Met Lab the hardware on 3 slow speed diamond saws, one high speed diamond saw, and a large abrasive saw all clamping components are Si Bronze, Nickel plated brass or cast iron. All screws in the clamps are Si Bronze.

Si bronze or Al brass would be my choices to mate with SS.
