Chain Plate Bolts - Thoughts?

[Cdn_bacon]

Boat has a Navtec rod and block arrangement which the deck chain plates connect to. Pulled everything apart to inspect condition (first time since I purchased the boat). Most of the bolts look ok but there's 2-3 that clearly have some surface corrosion (same as the blocks). I'd replace these bolts however the head design is special to fit in the chain plate brackets on deck. A hex head bolt won't work. So I'm down to reusing these or having new bolts fabricated. These original are bronze based.

If it's any consideration, I'm an inshore / occasional coastal sailor so the boat isn't seeing any crazy weather.

They don't look bad to me. Bronze. But you can call Fair Wind Fasteners: 401-344-9706
