It is also quenched and tempered at 800 f leading to its strength.
Grade 5 threaded rod equivalent.
The stronger and more heat resistant grade 5 threaded rod is made of medium carbon steel quenched and tempered.
There are astm specifications that have similar strength properties which may be easier to find in the form of all thread rod than their sae equivalent.

Same as grade 5.
This grade is for fittings flanges valves and pressure vessels.
Grade 8 has 0 28 0 55 carbon 0 030 max phosphorus and 0 050 max sulfur.
Strength is similar to grade 5.
It is also used as threaded rod in concrete and epoxy.
Grade 8 steel threaded rods are about 25 stronger than medium strength steel rods.
Sae threaded rods do not require permanent grade markings on the ends of the rods like many astm specifications do.
