I just took a closer look and answered my own question, it would be dicey to find a socket thin enough to fit a hex-head cap screw.

Burl,

With a yield at 180KSI, those should work. I would worry about the plating.
You could find a 9/16 (what it should be)-1/2 drive socket that would clear everything there, but there is still the problem that with a 9/16 hex will be very close to its working limit at the 70#ft recommended final torque for those fasteners. You will still need the hardened washer to accommodate the load on the flange surface.

I went down to the 'bolt room' at Coker Equipment in Gainesville with a sample. The Bolt Lady wander down a row and pulled out a sample, 12 hardness, 40 cents per. I had kept the original think washers and they had them as well. Red loctite and two hex drivers - they were the same diameter head and surface but were hex drive. The NO (Next Owner) hasn't had a problem with tjhem that I've heard of, after the many miles I put on the coach before I sold it.
Why Coker has such a good inventory in North Georgia of fasteners, I dunno, but pretty much anything that holds two things together they have and the Bolt Lady knows where on the roughly thousand feet of floor to ceiling bins it resides.
