BoltScience.com is a great place to pick up info on bolts. If you are working with slip critical joints better only rely on

I have a chart put out by Lamson & Sessions from
many years ago and would be glad to fax it to you.
It has many grades of bolt on it and gives the values
for dry and lubed bolts.
My e-mail is j.geisey@juno.com if you are interested and
give me a fax number to send it to.
I think the values that are listed are for 75% of yield.
The chart is at work, so I am going on recall. The only
warning that I would give is that bolts beyond 1.25 inches
should be tested rather than relying on the charts i.e. take
the bolts to yield (a small sample) and then use 75% of this
value. Then again if you are using very sophisticated tightening method or equipment, you could you higher values depending on the tolerance error that the method provides.
