SAE Grade 5 medium carbon steel quenched and tempered
1/4 thru 1 inch Yield (psi)=92,000 Ultimate Tensile Strength (psi)=120,000
One method used to calculate the value is the American Institute of Steel Construction (AISC) Manual of Steel Construction, Allowable Stress Design. Using this method, the allowable tensile stress, Ft, and the allowable shear
stress, Fv, are calculated as follows:
Ft = 0.33 x Fu
Fv = 0.17 x Fu
Where Fu = minimum specified ultimate tensile
strength for the steel material.
This stress is then applied to the gross nominal area of the threaded section to calculate the load in pounds.
