Anyone know what size / thread that tiny set screw is? I dropped it when taking the knob off and can't find it.....DOH

Shoot, yes. I'll edit the post. Total brain fart.

I replaced all the set screws in my knobs a few months ago. I took one of the originals to ACE Hardware and matched it up as best I can. I believe it was a M4-0.7x5MM set screw, but not 100% sure.

If you don't have an ACE around, send me a PM and I'll mail you one.

GA Architect is correct. It is a M4 set screw. It measures 4mm in length. Not positive on the pitch, my guess is it’s a 0.70. It matches up to a 0.70 screw I have. My chinese pitch gauges are rounded off and worthless in 0.70 & 0.75. If you are desperate you could cut regular M4 screw and dremel a slot for a standard screwdriver. Leave a nut on the segment you cut so you can straighten the threads out

Red, you are correct, the OEM screws are 4mm long......but ACE didn't have the 4mm ones, so I went with the 5mm. Also liked the fact they are stainless steel to boot.

Circling back to this thread after 4+ years, and just now ordering some M4 x .7 x 4mm set screws from BelMetric. Where does the time go, I mean, really?!!??

Yes this is correct.Also if you want to clean out the threads on the knobs where they screw on the shaft its 5mm-0.80 tap size.
