can 2-3/4" dia bolt row fit in W6 (6" depth)
can 2-3/4" dia bolt row fit in W6 (6" depth)
(OP)
I work in industrial and we typically use W8/C8 as minimum when bolted shear connection and 3/4" bolt is typically the minimum bolt size for steel structure.
But can 2-3/4" dia bolt row fit in W6 (6" depth) without issues with wrench clearance?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

You have to start looking at smaller bolts or non-standard arrangements below 8" depth.

3/4" dia bolt, standard minimum we use. can I use smaller? yes, but prefer not to.
even if I use W8 beam, existing beam is just 8" and I'm losing 1.25" depth because of grating.
maybe I should use 2 columns, 1 row of bolt.. instead of 2 rows, 1 column, no?

Why? I'm all for standardizing bolts, welds, and member sizes to simplify things but this is a plenty good reason to just specify what you need.

I see that from fabricators a fair bit when they're trying to satisfy the two bolt minimum rule in pieces that, like this one, are too small to manage that conventionally. I'm fine with it for small loads so long as the angle is checked as essentially to independent plates cantilevered from their respective bolt groups. Fine for small loads which is usually the case.
Here are some other, more robust alternatives including switching to a 6" channel.
