Another argument against galvanizing B7M bolts is in regard to the corresponding nut. A194 Grade 2HM nuts are typically used with A193 Grade B8M bolts. The B7M and 2HM specifications prohibit machining after heat-treatment. This is not an issue for the bolt, but it is for the corresponding nut. The A194 specification reads as …
