Many Licensor's specification specifies A193 B7 / 2H bolts for stainless steel flamges.
Use of galvanised bolt not seen at all for SS flanges.
Also note, A193 B7/2H bolts are not CS bolts. These are alloy steel bolts.
I did not understand the stage of your project . If youare planning to buy new one than buy ss bolts or can go for B16 / 4 bolts also.

Hello all,
Please recommend me the type of coated carbon steel bolts ( A193 Gr. B7 ) to use with stainless steel flanges.
I am sure no to apply galvanised bolts with SS flanges.
Our construction team is worried about the rusted of the carbon steel bolts to be apply with stainless steel flanges.
Please reply your recommendation for type of coating for bolts ?
Kind regards
Rahul
