<div>The tapped screw doesn't have to have a hex head...right? I'd prefer a slotted screwdriver...I think...?</div>

<p align="left">Ken -<br/>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/>Regards,<br/><br/>David Skolnik<br/>Hastings on Hudson, NY<br/><br/><br/>At 11:28 AM 7/25/2008, you wrote:<br/></p>
<blockquote class="cite" type="cite"><font face="Garamond">Hey, David,<br/><br/>Ive been gone this week, so Im just now replying. I went through this a while back. Those are 12x28 machine screws. I found a 12x28 tap at the hardware store (thats 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/>Regards,<br/>Ken Z.<br/><br/><br/>On 7/24/08 2:01 PM, "David Skolnik" <davidskolnik@optonline.net> wrote:<br/><br/></font>

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.
