What size are the screws that hold the infinity stops in place on the Pacemaker/Super Speed?
Thanks

Service Manuals only list paer numbers, pointed rear, flat front. Set screw type likely a #0-80. A #0-80 max body diameter is .06 inch; 1/16=.0625.

Thanks. My service manual copy only lists part numbers, too.

I usually just measure the OD of the screw then look that size up on a screw thread chart. Thread pitch can be determined by the number of peaks or valleys in 1 inch for U.S. screws or the numer of millimeters between thread peaks for metric.

I don't have anything currently available for measuring.

The infinity stop screws on the Pacemaker are #1-64. I have a set of thread gauges on hand and measured one under a magnifier. This is an uncommon size. You can get #1-72 in a hobby shop (model railway supply) - they will go most of the way into the hole, then jam up on account of the different thread pitch. You could probably use a #1-72 by filing the bottom thread off it so that it will protrude through the hole. But if you do this, make sure it is a brass screw so that you will not damage the thread in the infinity stop.

After a lot of searching through McMaster Carr, I see 1-64 x 1/4” screws. I might order some and see if they work.
