skinny Posted March 17, 2012 Report Share Posted March 17, 2012 ok SO I was working on my boat . I'm doing the new floor thing . when I pulled out the old ones I found this sticking up . it's not in a real good spot as it's near the bend in side for the water line. I don't know anyone that can weld it and I have heard mixed things about welding as it work harden the alum. inside boat look down from top outside boat Link to comment Share on other sites More sharing options...
irishfield Posted March 17, 2012 Report Share Posted March 17, 2012 I'm trying to figure out why it was there.. and where the head went? Is it counter sunk and covered with filler? If you want it gone.. remove it.. drill a clean hole and stick a rivet in it. Link to comment Share on other sites More sharing options...
Sinker Posted March 17, 2012 Report Share Posted March 17, 2012 Just leave it there. It was probably a leaking rivet that was replaced with a screw and sealer. S. Link to comment Share on other sites More sharing options...
Guest ThisPlaceSucks Posted March 17, 2012 Report Share Posted March 17, 2012 i would cut/grind the screw flush and reseal it on the inside. Link to comment Share on other sites More sharing options...

Guest ThisPlaceSucks Posted March 17, 2012 Report Share Posted March 17, 2012 (edited) that is the last thing I would be suggesting. you didn't! and to be honest, while i wouldn't want a full welded hull, i wouldn't think twice about fixing a small hole with a TIG.

Gerritt Posted March 17, 2012 Report Share Posted March 17, 2012 you didn't! Nor would I suggest it... I am not fool hardy. more then likely grinding it off will cause it to break the seal seeing as how there is no head on this screw, possibly causing even more damage.... even if he ground it off and didn't cause further damage, there is already little to no bite (thread) left on the screw on the thin hull... and cutting the screw will make matters even worse....boats take a pounding and vibration.... His best option is to drill it out and rivet it. Or you can be his boat mate with a bailer in hand. Link to comment Share on other sites More sharing options...
BillM Posted March 17, 2012 Report Share Posted March 17, 2012 Put a rubber cap over it so it doesn't snag on anything and leave it be. Link to comment Share on other sites More sharing options...
DRIFTER_016 Posted March 17, 2012 Report Share Posted March 17, 2012 I'm trying to figure out why it was there.. and where the head went? Is it counter sunk and covered with filler? If you want it gone.. remove it.. drill a clean hole and stick a rivet in it. And seal with 3M 5200 marine sealer. Link to comment Share on other sites More sharing options...

vinnimon Posted March 17, 2012 Report Share Posted March 17, 2012 A waterproof aluminum rivot will do with a drop of siloprene, and voila its sealed. Link to comment Share on other sites More sharing options...

Guest ThisPlaceSucks Posted March 17, 2012 Report Share Posted March 17, 2012 (edited) Or you can be his boat mate with a bailer in hand. perhaps it would "likely" leak if you did it... hahahahaha...

Gerritt Posted March 17, 2012 Report Share Posted March 17, 2012 Looks like a reverse countersink to me... looking closer I see a Robertson head?.... Thanks for the heads up Dave, this looks is a carpenters screw... it certainly does not look like a pan head metal screw upon a closer look... Looks like a standard carpenters #10 or #12 reverse countersink...?? Hence the reason for the filler! I would remove this screw asap... as you risk galvanic corrosion and as said... Rivet and seal. Thanks for making me look a bit closer Dave it was not easy to spot. G Link to comment Share on other sites More sharing options...

Guest ThisPlaceSucks Posted March 17, 2012 Report Share Posted March 17, 2012 (edited) i don't think you need to be a tradesman to fix a screw but keep pumping your own tires. besides, my academic days are behind me as i have been in the metal trades for the last year and a half. passed all my engineer inspections so far. to my knowledge the equipment i fixed is back in the mines doing their thing... besides, saying that the trades aren't "academic" is a great injustice to tradesmen as many are no more/less education than those in the science field.
