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.
