Good to know that the two most common wheel mounts/adaptors are 7/8" inch or 1" at the big hole end.

The 7/8" big end and 4.5" TPF ones are often for TC grinders and some surface grinders.
The 1" big end and 3" TPF ones are most common for 6, 7 and some 8" wheel surface grinders, and some Tc grinders..

If unsure of being a right or left thread one can set a 6" scale in the thread and eyeball view which way the thread goes.

Most surface grinder wheel mounts have a left-hand flange nut used on a one-ended spindle..
Most/many tool and cutter grinders have both, a right-hand one and a left-hand one/ one for each end of a double-ended spindle.
