I think the threaded rod was a B7 alloy. About 125 kpsi. I can't guarantee that we still get that same stuff.

HOWEVER! Bending stresses are much larger than linear stresses if you pull perpendicular to the shaft, and calculations get much more complicated (and depend on the tubing/housing size). We've always cautioned against using the jackpads as originally intended.
