radial pin specs

I am just curious as to what the thread count is on a radial pin? are they all the same? I heard some were 3/8-10, is that accurate?
thanks John

3/8 8.5 ( that's why it's hard to make your own ).
There's a Chinese knock off w/a different thread.

The Chinese Radial is approx. .375 X 8. The Uni-loc Radial is not an even number. It is .375 X 7.6xxx. We used a digital Comparator to get the exact measurements and radius's a few years ago.

Schmelke's radial pin and tap are 3/8-7.5 lots of variables out there.
Good luck.

I made some for joint protectors. On a Grizzly lathe the closest setting is A6 with a 46T F-gear and 60T G-gear. 3.3xx mm pitch x 9.45mm diameter.
