I was thinking LONG U-bolts Jim, like to fasten two 2 inch boom pieces
together or other such odd needs plus possibly a saddle and rigid plate. I
see DX Eng sells the SS or Alum saddles and a rigid plate in a set, but I
just need 1/2 of the saddle set plus the rigid plate. Also need to take into
account the fastening hardware. That ends up a LONG U bolt. I looked at DX
Eng data on the U bolts and see the ID, thread size and length but nothing
on the C length, the OA length from the inside of the curve to the end of
the bolt thread (unless I missed something).

Has anyone used U-Bolt-It in Houston to fabricate longer U bolts than
available in standard sizes? If so were they able to deal with small
quantities at a reasonable price (like 2 to 4 pieces)?

## what size bolt..and how long does it have to be ? The SS U bolts
I bought from DX eng have the longest threads I have ever seen on any U
bolt. They provide for bucket loads of
excess thread. They also come in both .3125 and also .375 sizes. You can
easily have enough thread to go through say a .75 inch thick AL plate..with
plenty left over for the nut etc.
