I have a new product project that needs a 1/4-20 threaded stud x 2"
long, attached to a 3/16" thick steel strip. I could just use a bolt
but the bolt head would get in the way. A carriage bolt would work but
would involve punching a square hole in the 3/16" strip. Is there a
off-shelf fastener that I could stake in the strip? I've seen such but
what do you call them and are they standard off-shelf part? Would it be
cheaper to bite the bullet and punch the square hole? (I hate square
punches and dies!)

It'll be a cool product and I'll explain all once I get legal status on
it. And, I have a new computer controlled wire wheel machine that is
almost done, it just needs programming and fixturing. WAY COOL! 1k
units a day (on paper) with almost no operator training. We're already
starting to make parts for three more. I could buy such machines from
Germany at $180k each.

Tap the hole and "Locktite" in a threaded rod. I just did this on a chisel
sharpening fixture I built.

Or thread it in and tack it.

Cheers!
