Shipping galvanized bolts and nuts

[iggs5886]

In section 6.6.2 of the "Specification for Structural Joints Using ASTM A325 or A490 Bolts" in the 13th edition of the AISC manual it states, "galvanized ASTM A325, A325M... must be assembled and shipped in the same container according to length and diameter." My company uses galvanized ANCO nuts and galvanized bolts for all bolted connections, and assembling the bolt and nut prior to shipping will defeat the purpose of the nut (and also wastes a lot of time). I am trying to find out if it would still be to the AISC code to just ship the bolts and nuts in seperate containers.

If the galvanizing fills the threads, lots of wasted time tapping or re-cutting threads. Pre-assembly is best.

But the ANCO nut is a self-locking nut. It uses a steel locking pin which engages the threads of the bolt as you tighten it. To undo the preassembled bolts and nuts the locking pin would have to be pryed back which is tedious and also defeats the purpose of using the ANCO nuts.

Sounds like the ANCO nut is not under the scope of the Bolt Council spec.

Here's the latest version of the bolt spec:

I see a requirement to ship them in the same container but not to assemble them.

My apologies on which section I called out the comment on assembling the galvanized bolts and nuts prior to shipping, it is actually under "Code of Standard Practice for Steel Buildings and Bridges" Section 6.6.2 (page 16.3-32).

If you wanted to push the legal angle, that statement is in commentary and thus non-binding.
