[How do I?] Cut A Blind Hexagonal Hole

Good to know, thanks.

I like the silver solder idea. Welding may distort the alignment or the socket itself. Silver solder will be very strong if you have a close tolerance on the mating surfaces. One thing to be careful of- in my experience the socket on a cap screw is not always co-axial with the shaft or the OD of the head. You may need to check a few and find the best one.

Forge it? Drill the hole out between the 'across flats' and 'across corners' size of the hex, heat it to red hot and drive a hex allen key into it.
 
I'm thinking I was once told the way to do this was to first drill the part to the same size as the hex & chamfer the entry. Then take a hex wrench, use a small burr to grind a recess in the end forming a hex "cutting edge". Then drive this make-shift broach into the drilled hole to cut a hex profile. Make sure there is bottom clearance for the chip.
Never tried it, but it sounded good at the time..
 
Ied try a 3/8" socket with drive end boarded out for shaft ?
 
Randy, I am glad you found something I was coming up dry.
I know I have seen it is a catalog, I just cannot find the right company or the correct search terms.

One other interesting product I found that is new to me is this:

Hopefully karim has enough ideas to move forward with the project.

I do, thanks everyone. I ordered one of the socket-drive parts referenced above. Will update this thread to point at a build thread assuming everything works out ;)
 
Cut the head off a bolt with a 3/8 hex socket drill for the 10-33 press it in the collar and use a 10-32 flat head screw.
