Stainless Steel nuts and bolts for Observatory

I finally discovered someone who can put a control system in my
observatory. To get prepared for the big day the work begins, January, I
need a fairly large number of nuts.

The contractor suggests that EBay is the place to get them at much lower
prices than the big h/w stores. Googling: "stainless steel nuts bolts
ebay", gives a ton of distributors. Can someone single out one or so of
these that has good prices?

Maybe DigiKey or Grainger have competitive prices.

In the meantime, I'll be looking for local prices in our small town.

We get a lot of goodies from the "Fastener Super Store".

They seem to be reasonable.

I can't tell you their prices are the lowest, but I can assure you
their inventory is top notch. This little vendor has supplied giant
Silicon Valley corporations with the oddball gotta-have-it-yesterday
stainless steel fasteners for decades. I spent so much time at their
counter, I felt like an employee.

fasteners from them for something like 20 years and have always gotten
great service and products. You can also try MSC, Tacoma Screw, and
Fastenal. Stay away from really cheap SS fasteners because they are
often just plain garbage.

Ditto Austin Bolt Co.

I'm small potatoes as far as they're concerned, but I've been doing
business with them for over 20 years and I've not yet gotten a nasty
surprise.

As a means of comparison, I went down to our local h/s store. Here are a
few prices for 100 boxed items. (I found the button bolts did not come
in boxes of 100. Probably not a big seller. I changed to Phillip heads.)

100 2" 1/4" Phillips, $48
100 1/4-20 fender, $29
100 Nylock 10-24, $21
100 Nylock 1/4-20, $12.50

Try www.mcmaster.com. They have decent prices and fast service. I've also
dealt with MSC and Fastenal.

Also try surplus places:

Working in a chemical plant for a steel erector as an ironworker, we had to
use 'Anti-seize' on all the stainless connectors. Else we could not take
the nuts off the bolts without Air-arcing

McMaster-Carr is generally cheaper than Grainger.

McMaster has excellent service, too. For more woodsy sorts of
products, McFeeleys is also good.

The issues seem to have been strength. So you could clamp a bolt in a vise
and then thread a nut onto it and use a big breaker bar or torque wrench to
see how much it will take. If it survives, examine the threads to see if
there is any sign of distortion or damage. There is also the issue of
galling, which can be minimized by using an anti-seize compound.

You can also do a hardness test with a center punch and a hammer which
should be dropped from the same height to compare the new nuts to some known
good ones. A magnet test can determine if it is alloy 18-8, which is less
expensive and slightly magnetic, or alloy 316 which is essentially
non-magnetic and more costly.

Not true. Many alloys of stainless steel are magnetic. Some become

magnetic by working. For example springs made from 302. Some are
intrinsically magnetic, 17-4 and 15-5 come to mind. 18-8, more
commonly known as 304, is almost completely non-magnetic. If a
fastener is quite magnetic it is not 304 or 316. These alloys, even
worked, do not exhibit significant magnetism. Fasteners exhibiting
significant magnetism that are not specifically identified as being
made from a PH alloy or a 400 series alloy are almost certainly low
quality fasteners made from questionable materials and should bge
avoided.

mostly non magnetic, it'll stick weakly to stong magnets.
