Does a Lower Bolt Shear Limit Affect the Overall System's Maximum Shear Force?

[Ry122]

if a beam has a shear force limit of x
and a bolt that is passing through the beam has a shear force limit of y
and y < x would the maximum allowable shear force for the whole system become y?

So far the whole system is a mystery to me. Why don't you describe the exact case?
