Bolt torque to stress
WebNOTE 1: This torque table applies for 1/16” and 1/8” thick homogenous elastomeric gaskets. The pressure rating of the material may vary depending on the grade. NOTE 2: The above-mentioned torque values are based on the maximum blot stress of 60,000 psi. Bolt yield should be at least 80,000 psi. http://www.repairengineering.com/bolt-torque-chart.html
