Leadscrew Backdriving Force Question

I'm looking for an equation to calculate the axial force in the direction of gravity required to drive a acme leadscrew mounted verically given the leadscrew info.

Basically I want to know how high a load I can put on the nut before it starts moving, or how much the nut can hold without moving.

Thanks,

Guy

Depends on the lubrication. If none, I would think it could not turn under any force.  If you know the coefficint of friction it can easily be calulated.
