tube socket legs?

[NordicNorm]

Howdy All!

I've searched the inter-webby thing with no luck.

Does anyone know where I can find a source for tube socket "legs" (20-30 mm with M3 threads)?

Thanks!

Cheers,

Do you mean standoffs?

Try MSC, Grainger, and McMaster-Carr.

There are M3 threaded standoffs in a variety of lengths from 3mm to 52mm listed under the above link.

Digikey has M3 standoffs too. One could also use a long machine screw and a regular cylindrical standoff - or a piece of 1/8" pipe cut to size.

Not sure exactly what you mean. If you want to 'raise' the socket of a PCB, i.e. extend the socket legs, I've seen tubelab using pieces of thin brass tubing. But since you are asking for threaded M3, I suspect you want to stand off (or recess) the socket from the chassis opening.
In the absence of having anything other handy, I used pieces of stiff PVC hose (the kind used to connect fridge water dispensers to the water line). They are easily cut to size and compress a little when the screw/bolt is tightened. The result has a little 'play', which worked out fine for me, because the openings for the tubes I cut into the Lexan cover of one of my "temporary" enclosures were not exactly done (true DIY...), so little wiggle-room allows me to get the tubes in properly without causing stress on the sockets/PCB.
For a final, properly machined enclosure the threaded or vinyl/aluminium tube versions are certainly preferable.
