Does anyone have a good breakdown of what spark plugs have removable tops and threaded studs underneath like those used on old Briggs and Stratton engines, as well as the thread size?  Looking for the tread size for the top on a J8c, as I would like to order some nuts for on my old Briggs and Strattons.

I used to just steal them from old plugs because the new ones would sometimes not have them. The tops were loose and the plastic wraps of the plug packages often leaked. Good Luck, Rick

I know I've seen them with different sizes. One nut won't fit the same plug. that's where a good thread guage comes in handy.

That may be why most nuts I have seen for this application seem to be made to fit a little loose,

Take the old plug to the hardware store and see what fits.

If I had one laying about, I could probably figure it out. Probably a 6.

That would work, except everyone around here only sells this small stuff In packs of 20+, no one sells anything under 1/4" loose, I could dig through my personal stash, the nuts I plan to order are brass thumb nuts.

Some wire strippers also have the ability to cut small screws. I have used these to find the size & thread for small threaded items.

Figured it out, J8c is 8-32 for the top, just so happened to find a pack of 8-32 hex nuts while looking for something and tried them on a whim.
