Subject: Hole width for .25 pots?

From: "c45a6" <clone45@...>

Hello!

I am working on a panel that will have a few Alpha potentiometers
involved. (mouser part #31JN405)

The specification sheet shows that the diameter of the shaft is .25
inches. It also states that the threading is M7 x .75mm... whatever
that means! I have a similar potentiometer floating around, and I've
noted that it doesn't fit into a .25 in hole. The threading makes it
wider than .25 in. Unfortunatly, the specification sheet doesn't
show
the total width for mounting.

Does anyone know that value off-hand? I downloaded a few sample
front
panels, and the closest thing I found was a hole that was 2.82 in. I
don't have my tape measure nearby, so I can't tell if that's in the
ballpark or not.

Thanks!
