Pretensioning Different Grades of Bolts
Pretensioning Different Grades of Bolts
(OP)
Hi There,
I'm wondering if anyone knows how to relate the turn-of-nut method for pretensioning bolts, to weaker and stronger grades than the standard A325. If a bolt has a dramatically lower, or higher yield stress than typical - shouldn't the rotation beyond snug tight be modified to attain 0.7Fu? Does the bolt pitch account for this?
Any thoughts would be greatly appreciated.
Thanks!
