Thread Locking Compounds

[steveneddy]

You see it in consumer and professional electronics on the nuts and bolts holding PCB's down and other panels together.

I am looking for a product that you can put in the threads and it runs down onto the nut to prevent any vibration loosening from occurring over time.

Loctite is not what I am looking for.

This isn't applied to the threads of the fastener and then the nut screwwed down onto the thread locking material.

After fastening the nut securely you put a drop or two on the threads of the fastener and it runs a little down onto the nut as an extra safety measure.

Anyone know what I'm describing here - and if so where to acquire such material or compound?

Nail varnish.
Loctite and parts suppliers do carry this type of thing but regular cheap nail varnish is suitable and generally available.

Loctite is a brand and is what you want. I use Loctite 222 (purple band) for #4 through #8, anything bigger I usually will use the blue, 217 I think.

Marshall used Glyptal insulating varnish.

Are you sure? It seems like blue loctite is really the best solution. Adhesives are much more effective at the interface of the two surfaces instead of above and around the interface. Wood glue, for example, works great inside a joint. Applied outside the joint, not so much.

Apparently it's called "locking patch": http://bb.steelguitarforum.com/viewtopic.php?t=130560

And Vibra-Tite looks like one brand you should be able to find in small quantities. This might be a winner: http://www.vibra-tite.com/products/vibr ... hreadmate/

I use blue threadlock on every nut and bolt, from 4/40 up thru 10/24. Usually on top after the nut. The generic works fine.

I use loctite on the Harley, nail polish on screws in an amp.

Yep, ND Industries Vibra Tite 3 as a thread locker works well. It is not the lacquer that is "painted on" that the OP requested though.

I haven't used any type of thread sealing product in my electronic projects, but I do use a wicking type loctite on some firearm fasteners. It is #290 green, (also packaged, and sold as guntite). It is easily removed, and doesn't seem to get as hard as the (higher strength) red, or blue.
I have also used nail polish in the past with good results. I don't know if anyone's done any tests to determine which colors produce the best tone though.

Nail polish. That's an awesome idea, because I live with a 16-year-old girl. Mmmmm.....sparkles....

Loctite is good but pricey. There are other equivalent thread-lock compounds. I just grab cheap stuff from the local $2 emporium

I use 271 on stuff that i can apply beforehand.

There is a Loctite product for locking already assembled parts.

The green Loctite package says that you need to use "localized heat" to disassemble parts.

The loctite product is 7400 Varnistop, cat no. 27950.
