Nylock nuts or Keps nuts?

[Willabe]

The nylock's are quite a bit less money.

But I wonder if for some things like bolting down a ground lug they will give a better ground connection to the chassis?

I vote kep nuts all the way inside an amp. Stainless steel kep nuts are not expensive if you buy a box of 100 on eBay. I would definitely rather have a kep nut for any ground lug.

I find nylocks handy for situations where you want to lock the nut but don't wan't to really torque it down tight, like mounting a reverb tank to a chassis. They would be good on speakers too.

What about tube sockets?

I haven't been using any nuts on sockets for several years now. But if I had to, I'd use keps just because I have a good supply in sizes 4, 6, 8, and 10. If I had nylocks on hand rather than keps, I'd use them on sockets. But I would not use a nylock on a ground lug, even if I didn't have keps. I'd use a star washer. I just like the way keps or external tooth stars bite into the chassis, making a very good electrical connection. Nylocks will not do that unless you put a star washer under them.

Ok.

That's what I'm thinking too.

I prefer keep nuts as well.  Actually I use Allen Bolts and Keep Nuts mostly everywhere.  I buy in quantity from Mcmaster Carr, but on tube sockets I prefer to tap and use allen head with a drop of blue locktite.
