Frank, The thread clearances on a nut and bolt are too close, with
plumbing there is a tapered thread. R/Jay Respectfully, Jay K. Jeffries Andros Is., Bahamas As scarce as the truth is, the supply has always been in excess of
the demand. -Josh Billings From:

[mailto:owner-personal_submersibles@psubs.org] On Behalf Of ShellyDalg@aol.com Hi Guys. I've had lots of problems with SS galling in the past,
mostly with just bolts. Although the bolts weren't in salt water, they were exposed to the
weather, and sometimes acids, which is why SS was used. I did a job and we used
SS bolts and cadmium plated steel nuts with SS washers, and although the nuts
got a little crusty after about 2 years, they still came off fairly easy. I put
regular lithium grease on them when we first installed the system ( stainless
exhaust ducts in a computer chip facility ) and because modifications are often
necessary in those companies, it was always the practice before to just use a
big breaker bar and spin the bolts until they broke. I always hated that approach because often times it
was necessary to dis-assemble sections that weren't within the scope of work
due to access on some of the flanges. Sometimes we'd have to go back up the
line several sections and break it there so we could pull out the pieces we
wanted to change. Of course, the salesmen bidding the jobs didn't account for
the extra labor, or the material, and it was always a struggle to make a buck. By using the cad nuts and grease, it worked most of
the time. The engineers who wrote the specs for SS hardware didn't like it
much, but it worked. I wonder if Teflon plumbers tape would be an
alternative ? It's cheap, easy, and won't degrade with salt water. Frank D. A Good Credit Score is 700 or
