A325 Bolts

A325 Bolts

A325 Bolts

(OP)
Has anyone encountered A325 bolts from China with red stains.  Do you know anything about what is causing this problem?

RE: A325 Bolts

When and if your source is unreliable, I would test
a number of these bolts to ensure that they are or
meet the specs of A325 bolts.

RE: A325 Bolts

I don't think these bolts are used on DOT projects.  Last time we got a batch from Canada and CT DOT made us get rid of them eventought they were to anchor railings on top of parapet walls.
