With a minimum tensile strength of 150 ksi and a minimum yield of 130 ksi grade 8 has a higher tensile and yield strength than other steel grades such as grade 5 and b7. The appropriate fastener specification will depend on the application. For proof load yield and tensile strength values for threaded rod refer online to the astm sae and iso mechanical requirements for steel fasteners chart or the industrial fastener institute website and handbook which can be found in resources. It is also quenched and tempered at 800 f leading to its strength.

Technically all thread rod made from a36 steel should be ordered to a fastener specification such as a307 grade a a307 grade b f1554 grade 36 or sae j429 grade 2. In the case of a 8 8 grade bolt the first figure signifies that the tensile strength is at least 800mpa.
