I checked with Portland Bolt before i sent the email , they have the material 
and are quite knowledgeable , however , they weren't too interested in such a 
small order of only 3 pieces since they had to manufacture them , didn't say 
they wouldn't do it , just that the setup expenses wouldn't make it very cost 
effective for me.

##  I required  12 x anchor rods...  1.125"  diam  x 60"  long...with 6" threads
on each end.  [105 ksi].   Local fastener outfit  just orders em from portland bolt. 
If I had ordered em on line from portland bolt.. they would have been 30% LESS..
and that including shipping to my door.  They were $90.00  each, from portland bolt. 
Then I had to get the  72 x  massive heavy hex nuts  [ 1  13/16"] + flat washers etc. 
Then had to get the 18 x 1" diam x 3" long  ASTm  A-325 bolts  + mating 1  5/8"  heavy hex
nuts  + washers. 




I called Atlantic Bolt Inc and they have the bolts in stock along with the nuts 
and washers , for about $22 each , UST wanted $204 for the three...

## UST these days reminds me of the  $500.00  hammer's  fiasco in the US,[defence contractor's]
back in the late 70's.   I had my local trucking co stop by the UST factory on his way 
back from bakersfield... to pick me up a 20' x .375" wall, heat treated 4130, 107 ksi
chromolly mast.   You  don't even want to know what that thing cost.  It was 80%  more than
what tashi tower's  charges..for the same thing.  His is actually better, since it's 120.2 ksi. 
[$750.00   vs  $1350.00]

I required a doz  1/4" bolts  for my HDX-6809... used to bolt the rotor and bearing plates into place.  Now these
things are just G-5 galvanized bolts, with counter sunk heads.  $6.00  each !  And  6  per shelf.   And they are supposed
to support  600 lbs of weight between em =  100 lbs per 1/4"-20  bolt.
