Which bolt should be used for a beam support with different yield strengths?

[engtobe]

I have calculated two diameters of a bolt to be used in a beam support using a plate at each side supported in a cradle with a hinge pin.

i used shear strength and a constant load to find the diameters the reason i have two different diameters is because the plate and bolt have different yeild strengths

the plate has the lower shear strength and resulted in a bigger diameter of bolt.

what bolt should be used?

thanks for any answers

You design a bolted joint per the yield strength of the bolt, not the material it's bolting (unless the geometry has stress-limiting factors).
