In December 2015, ASTM committee F16 approved the new F3125 standard, which combined six structural bolt standards, A325, A325M, A490, A490M, F1852, and F2280. The goal was to clean up inconsistencies within those various standards and combine them, so that future updates would be easier and less costly.
The goal was not to drastically change any of the requirements of the Bolts, as they had been used and functioning in the marketplace for decades without major issues. However, in order to better align with each other and with current design standards, minor changes were made. The most notable change was the increase in mechanical properties of large diameter A325 bolts. Originally, bolts ½” through 1” diameter had a minimum tensile requirement of 120ksi, whereas for bolts above 1” diameter, the requirement dropped to 105ksi. AISC design guides had used the 120ksi value for design loads all along regardless of bolt size, so this increase by ASTM aligns the design strength with the actual strength.
