Bolt Depot and McMaster Carr.
Bolt Depot also has stainless nuts with serrated flanges. I'm going to try
them.

One thing about stainless fasteners, actually two things:
yes they stretch under load so proper torque is essential. Torque, operated
to heat things up and retorque. Otherwise you get to watch stuff fall off.

Anti Seize, good anti Seize is a must.  Other wise, while torqueing the
threads will gall. While this may help the loosening problem, it can make
removal down right impossible. Stainless nuts on regular steel studs do have
this problem but whenever stainless studs and nuts are used, beware.
