My apologies. I was picturing a socket head cap screw, an item
that, like my digital caliper, I try to find a use for when I can.
Yours would take a standard 7/16th socket, which I already carry.
Given what tends to happen to the slot in those screws over time, the hex
is probably a good idea. Thanks again.<br><br>

I’ve been gone this week, so I’m just now replying. I went through
this a while back. Those are 12x28 machine screws. I found a
12x28 tap at the hardware store (that’s how I confirmed the size), but
nobody makes 12x28 screws any more. I bought a 1/4x28 tap and a #3
drill and replaced the originals with a hex head cap screw. Quick
job, works great.<br><br>

<dd>I have devoted an unconscionable number of hours to this pursuit, to

There must be someone who knows the history of this screw, why these
dimensions were employed and when it might have changed. At this
point it seems a matter useless curiosity, nothing more.
Thanks<br><br>
