I am grateful for your response, so it likely seems odd, or tiresome that
I would challenge you on this, and the fact that you have found a quick
and effective means of addressing the problem is really the relevant
point. It becomes little more than a quirky footnote that the
screws (all three) from my model O #160774 are <i>not </i>28 tpi, but
something slightly more. I did speak to someone in the trade
(screws) who gave me reason to believe that there still are some 12x28's
out there, but it would be of little use to me, had I the need for a
replacement. Thanks again for sharing your suggestion. I'd
just hate to be the unfortunate technician who, someday, goes to tighten
those pedals, only to find he lacks the proper hex tool. One more
item to start packing in.<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

28<font face="Garamond" size=6>+</font><font face="Garamond"> tpi.
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>
