Individual assembly drawings will show special requirements.

(4) Socket head screws and 12 point head screws with full body are also grade 8.
The flareless fittings are best assembled with number of turns after some initial tightening or running to the stop provided and then tightening with an additional 5 to 50 pounds feet of torque. No standard data has been prepared for the flareless fittings.
