Wily well nuts
My first experience with well nuts, please don't laugh :)
Installed #10-32 well nuts in 1/4" plywood of trailer interior wall - there was no studs nearby to run tapping screws.
The plywood is 1/4 - really 1/4, not 3/16. The nut was for material thickness 1/64-3/16, see first line in #10 category: 1/64-3/16.
I know - shoudda woudda used a bigger nut, but I thought my wall was 1/8, and after drilling the hole didn't want to drop everything and order different nuts.
Tightened the nut, all is good, holding the device nicely. Then removed the device that I was mounting, and the loose nut quickly pulled itself into the wall and disappeared, now it's sitting in the wall in insulation somewhere. Hmm... This wasn't supposed to happen.
With the next nut I was wiser, and put a washer under the lip, so that it couldn't escape into the wall again.
Now, I don't think that any washers need to be used with well nuts. So why did it pull itself into the wall? Maybe I made the hole too big (to tell the truth, I drilled with 1/4" bit and then just filed it out wider). Also, the wall was too thick, - but if you look at the catalog, there are no #10 well nuts for 1/4" wall, nothing between 7/32 and 5/16. (Though with the washers that I had to add, a nut for 5/16 thickness would probably do fine). My device is 9 lb, so #8 nuts don't inspire much confidence.
