F1554 Gr. 55 anchor bolt has yield strength of 55 ksi
F1554 Gr. 105 anchor bolt has yield strength of 105 ksi.
Sideway shear strength of the bolts are said to be 0.6 times the tensile strength so in case of grade 55 bolt, it's 33 ksi.
Let's take the case of 5/8" epoxy or chemical anchor bolt post installed (meaning after the concrete is placed) to the concrete pedestal or base. For shear or sideway lateral movement. Have you encountered cases where the concrete pedestal have greater shear resistance than 33 ksi in a 5/8" anchor bolt? What is the maximum shear strength of concrete pedestal have you come across?
If none and you are just considering the shear resistance. Why get the Hilti Gr 105 instead of just the Hilti Gr 55 (or other brands)?
