Guest Posted April 26, 2010 Share Posted April 26, 2010 Researching the issue of keel bolts on the net is quite interesting. There seems to be a lot of comment that stainless keel bolts are not good due to its corrosion potential in the absence of oxygen. Also seems that they should be checked and tightened as much as every two years. The specs for my boat refer to copper rod being used for the keel bolts ..is this a better option than stainless ? Why do most production boats use stainless keel bolts if they are susceptible to corrosion? Link to post Share on other sites
Guest Posted April 26, 2010 Share Posted April 26, 2010 the most common bolts nowdays is 2205 stainless steel, which doesn't have any of the oxygen issues and is stronger than std. I wouldn't have thought that copper bolts in a keel would be common, there most likely silicon bronze. but you never know. Link to post Share on other sites
Guest Posted April 27, 2010 Share Posted April 27, 2010 Can that 2205 be purchased as 12 mm threaded Rod? Link to post Share on other sites
Guest Posted April 27, 2010 Share Posted April 27, 2010 Almost all the older (pre 1960) boatbuilders used hard drawn copper for keel bolts. We used it until the early 70s after which we switched to monel. Burying the older stainless in a lot of wood was not a good idea. Modern construction no longer involves a lot of wood. If Gary (LEB) doesn't know not many will. Link to post Share on other sites
Changed 10 Posted April 27, 2010 Share Posted April 27, 2010 I used silicon bronze for keel bolts on aboat that I rebuilt and it was eeeexxxpensive. I'd go the stainless. Link to post Share on other sites
ScottiE 174 Posted April 27, 2010 Share Posted April 27, 2010 I'd do away with keel boats all together and go a multi! Link to post Share on other sites
