slinkymalinky Posted November 5, 2008 Share Posted November 5, 2008 I have a small problem that I hope doesn't become a big problem. I attached some rod holders to the aluminium railings on my Quintrex and riveted them to the railing for added security. Stupidly, I only had 1 aluminium rivet left of the correct size so one got riveted with a stainless rivet, coated with zinc corrosion inhibitor. The stainless rivet has snapped, leaving part of the rivet inside the tubular railing. How bad a problem is it? Is the potential for electrolysis inside the railing worth cutting it off so that a bit of stainless doesn't eat thru the deck and drop into the hull, causing more serious problems?? Any other thoughts? Cheers, Slinky Link to comment Share on other sites More sharing options...
pelican Posted November 5, 2008 Share Posted November 5, 2008 (edited) Forget it - go fishing. Very little surface area and already coated in duralac so unlikely to cause a problem Not even going to ask how you shear a rivit off but you must have had a marlin on the line or a child using it as a monkey bar. Some manufacturers actually used to have a 10mm hole drilled near the ends of their railings compresser air jet in one end and out it comes ( depends where the holes are if any).. Get a spare rivot an a magnet and confirm it isn't magnetic. Some are stainless rivots but have steel mandrils and that would concern me a little more but it is in an area that has little moisture.

Cheers, Slinky Same as Slinky says - depending on what material the mandrel is would only be a minor concern The further two metals are apart on the galvanic series chart, the greater the potential current that can pass between them.
