Allowable joint fastener pre-loads
Allowable joint fastener pre-loads
(OP)
I'm sure this has been talked about before, but I am not finding exactly what I am looking for.
To be specific, I am looking to use M8 12.9 (S ult 174ksi) fasteners for a flanged joint for a pressure vessel. What is the maximum allowed tensile pre-stress allowed in the fasteners?
Thank You

Check with your gasekt supplier, see what they recommend for an applied seating stress, work from that.

Refer to ASME PCC-1. You'll find what you seek there.
