Re: Grade 8 bolts in place of A325 bolts

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Anand,

I don't have the spec you are asking for handy, but Grade 5 is the spec that
is closest to A325 Bolts.  In fact I purposely avoid Grade 8 and A490 bolts
in tension unless they are pretensioned because of their low tolerance to
fatigue.
