No. You should not use galvanised fasteners with stainless steel connectors. Stainless steel fasteners should be used with stainless steel connectors. Galvanizing (zinc) and stainless steel are considered to be dissimilar metals which can cause the zinc to corrode when placed in contact with the stainless steel. This would result in the galvanised fasteners losing their protective coating faster than expected. Hot-dip galvanised and stainless steel components should not be placed in contact with each other.
