Torque #, lock nut on the front fork piston rod?

What number should be used to torque the lock nut on the front fork piston rod?

When I was torqued the fork cap to the piston rod, The lock nut seemed to back off the piston rod.

Note: I was tried when finishing assemble and noticed this after running the build in my head. So I will take the Fork cap off and double check the lock nut to the piston rod.

If the lock nut is loose, I assume I can hold the piston rod (trying not to damaging the piston rod) with pliers and tighten the lock nut. What number should be used to torque the lock nut on the front fork piston rod?

Thx,
