Speed nuts for Gretsch mufflers

[dcdrum]

Does anybody know what size these are, and where you can get them? The muffler on my 4160 snare has screws, but no nuts!

I picked up #6 flat speed nuts at Lowe’s, but they’re too big. I assume #4 must be right, but the only ones I can find online are these:

Amazon.com

I’m not sure if 4-40 is correct, or if it matters? 40 is just the thread pitch, right?
Photos are from my wood Gretsch snare, but they look to be the same size screws (as do the screws on my Gretsch tom’s)

I get mine at an Ace Hardware near me. I don't know the size as I just bring the bolt with me.

OK. Seems like this is one of those things that an old school hardware store is better for.

I hate those things. Though Gretsch probably saved a few pennies per set.

I went ahead an ordered the speed nuts from Amazon. I didn't want to run around to any more hardware stores without knowing for sure they'd have them. 4-40 worked perfectly, though they are a bit of a pain to install on the inside of the muffler. Not easy to hold them in place with the muffler arm and mounting plate in the way. I'm sure it would be much easier on the flat inside of the shell, like they're used for the strainer and butt on my wood shell Gretsch snare.

Now I have 22 speed nuts left over for all the other potential Gretsch repairs in my future.
