threaded rod allowable tensile stress
threaded rod allowable tensile stress
(OP)
I have seen 9000 psi used as an allowable tensile stress for threaded rod on several load tables from manufacturers, etc. Anyone know how this value was derived?

Several different factors can contribute to safety factors much greater than typical structural specifications:
- MSS-SP-58 (and presumably whatever Hilti product you're looking at) was specifically developed for pipe hangers and supports. Safety factors for mechanical applications tend be grossly over-conservative to account for fatigue and other accidental loading conditions, and
- AISI 1010 doesn't specify any particular strength but only the composition. Unless tested or specified, the steel MAY have different properties/strength variabilities than A36 or A992.
