Screw size for Bridgeport

[Anzaniste]

Can any one tell me what is the screw size for the locking screw for the dial gauge rod on the side of the head. (I hope my terminology is understood)

If you mean that little boss on the side of the head, where you can put a rod to hold a dial indicator, mine's 1/4-28. But then, it's also an import, so your mileage may vary.

Yes thats the little monkey. My machine is a genuine Bridgeport.
