'Looks like' and 'being' are two different things.
The true 'import ball-screw' (please don't call it a Radial) is not
center drilled yet this one is. That's not to say that someone after
purchasing the pin to install didn't center-drill it themselves.
Chris Hightower used to offer a 3/8x8 ball-screw pin but I'm not
sure that he still does. If it's his, he would recognize it.
Knowing the diameter of the bolt 'that fits' would be helpful.
might be one of my real early cues
i only used radial for a couple years.
i could be wrong but i THOUGHT i always signed.
i'm not 1000% sure of that though
I thought Capone's were laser engraved on the screw.
