>From AISC, 5th Edition:

S6x12.5, 2" ga, max bolt 5/8" (rivet, actually) dia

S5x10, 1 3/4" ga, max bolt 1/2" dia

S4x9.5, 1 1/2" ga, max bolt 1/2" dia

S4x7.7, none shown, but should be the same as S4x9.5

S3x7.5 & S3x5.7, 1 1/2" ga, max bolt 3/8" dia

I would note that two 5/8" bolts in the flange of the S6 remove 41 percent
of the flange area, assuming 1/16" oversize for the bolt holes.  You may
want to consider another kind of connection.
