Re: STEEL: Galvanizing of High-Strength Bolting

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Twist Off Bolts are generally manufactured to ASTM 1852 and the material is generally A325.  I say generally because you can also get A490 twist off bolts.

I thought twist-offs were covered by a spec other than A325.
That is, the material strength may be the same, but
twist-offs are covered by F1852.  I'm not familiar with
F1852.  Is the material chemistry the same?

I'm not arguing with the mechanical galvanizing comment.
