Thread Size for Jack Nuts?

Post by gtrmstr53 » Sun Oct 25, 2020 6:56 pm

silly question, but i haven't been able to find the answer. what thread size do thonkiconn (and other) 3.5mm jacks use?

i'm thinking of buying some black nuts/washers to color code my inputs and outputs, but thonk doesn't seem to list the answer and my nuts didn't fit any of the tester bolts at home depot :/

I would *imagine* 0.75 but best to find datasheet - weren't these developed from Kobiconn sockets (available via Mouser?)?
And/or use one of those thread measure tools (forget the name)

Neither. M6 x 0.5 covers all the Chinese jacks.
Switchcraft tinijax are different.<-- But if you got in on that mono Switchcraft 500jack box surplus deal awhile back, those are M6x0.5 also.

You're not going to find this thread at a hardware store. Or even most fastener sellers. You can buy taps and dies to make your own, but even these will often be special order.

Similarly, the M7x.75 of many pot bushings is less common. But that one's not as hard to find as M6x.5.

Yes, M6x0.5 for the common Chinese-made 3.5mm jacks. It's not hard to find more or less identical replacements for the standard knurled nuts that come with the jacks, but you're not going to find a wide range of different colours and styles ready-made and available in small quantities for customization.

I tried to find black nuts for my TTSH, and drew a blank apart from the befaco nuts...

its a weird gap there, but when modelfixings.co.uk couldn't help, I gave up...
