Anodes must be replaced when they are 70% eroded.
Martyr ( Canada Metal (Pacific) Limited ) only uses mil-spec mil-a-l800l alloy in all of their premium marine anodes.
This alloy helps the anode erode inward giving the anode a sandblasted appearance.
Canada Metal uses a special steel combination fastener that makes it possible to use their Ball drive, which is a hex driver with a universal ball tip (Ball-drive is Sold Separately).
