[R-390] R-390A PTO ground strap screw

[KR4HV]

Bill, just checked with my contact at Fastenal.  They have the square #4-40
Stainless Steel nut.  Their computer showed about 5000 in stock at various
company locations. The Fastenal part # is 0170846.  They sell these in
"each" quantities for about $0.45ea.  May take your local Fastenal store
about 3 days or so to get one or more for you from another branch store if
they don't stock them.

BTW, the price is a lot more per unit for this square nut than standard SS
#4-40, #6-32, #8-32, etc. hardware in bags of 50.  Guess they don't sell
many square ones nationwide.

Hope this makes your day a little brighter!!!

73,

Do you think they would have the square 4-40 nuts used on the shaft clamps?
I lost the one for the BFO shaft a long time ago. I've since put on a hex,
which seems to work well enough, but it doesn't seat down into the clamp.

Hi Bob.  When you find out exactly what type screw it is you may want to try
Fastenal(www.fastenal.com/).  I am not connected with them, just a customer.
They are an industrial supplier and can get just about any screw & bolt made
with any thread count, US, course or fine and metric) .  They don't cater to
the individual trade but will sell to us. Most of their locations (check the
computer, they are all over the US) stock down to 4-40 or 6-32 in stainless,
cadmium and brass but I have just gotten some 3-48s, 2-56s, 0-80s & M3s in
different lengths in stainless from them (they ordered them for me and it
took all of 3 days delivered to their store). 

I particularly like the stainless nuts with captive star washers in 4-40,
6-32 & 8-32, etc.  Work great in tight places. They sell them in bags of 50
or 100 in these sizes.. 

You may have to order 25 or 50 of a part number as they typically don't sell
by "each".  They are much more affordable than the hardware or builder's
mart.
