The harder steels are less susceptible to galling. You can select stainless steel bolts from the ASTM A193 family of steels. They will still be a type 316. There are some lubricants and anti galling compounds that will not wash off with water. Check out Synergistic Coatings, Neverseez, or Loctite. Synergistic Coatings, Neverseez, and Loctite are also anticorrodents. Some are fluorcabons, some are metallic oxides with petroleum vehicles, and some are epoxies. Get some samples, and product literature and see what strikes your fancy. Other factors are the operating temperature, pretension load, and reuse (not advisable). Take care in specifying installation guidelines.

This specific application is under water, so a coating may not work. Also, the water is high in chloride and sulfate ions, so galvanic corrosion of dissimilar metals is likely. Our contractor has suggested making the bolts a 400-series stainless and furnishing 316 stainless nuts as specified.
