High Tensile Bolts aren't all the same

This won't be news to some.
High tensile bolts have different max torque settings as I found out earlier this week! I replaced the rear stub axle bolts with ones I got from a local fastenings supplier (grade 8.8) but found they stretched. Rang the place up who said I'd exceeded the max toque. That could have been nasty. Doing a trawl on the t'internet reveals tables for such stuff -
Lesson learned!
