turn of the nut for A449 bolts?

(OP)
Are there published recommendations/requirements for installing A449 bolts by the turn-of-the-nut method?  RCSC only covers A325 & A490.

(OP)
They're the same strength, but I believe a different thread configuration, which would change the turns.

I can't really back-calculate it, since the A325 turn requirements are lumped and simplified.

If the thread pitch is the same -- UNC -- then Turn-of-the-Nut will work.  Watch your Length vs. Diameter ratio, as per RCSC spec.
