    Contact your strut nut supplier. I know Unistrut lists recommended torque values on their website. I'm sure other manufacturers do the same.

    Brother

    Unistrut or world known companies only publish the torque value for the Bolts

    We have checked the same with online assembly calculators http://www.engineersedge.com/calcula...orque_calc.htm

    Its less in proportionate to the thickness but our buyer doesn't agree so need help with your comments

    In arguments between competing "theories" I have found the only way to resolve them is with actual real world tests.

    Back in the day we had books with a pencil and paper accompanied with a headache and itchy scalps.
