u- bolts?

[bvblack]

Is there a standard that u-bolts are made to; as far as radius, depth, diameter etc. ?

[loose nut]

There are different kinds of U-bolts, square, round etc. although they may not be classified as u-bolts. As far as the ones used for bolting up piping there seems to be a standard. All the ones we get from different sources appear to be the same. Can't say if that is universal.

I'm sure there is a standard; there is a standard for everything these days.
