looking for parts

Hello,
I’m looking for some springs ( this one is from an Ultrafire 501) the one on the module that makes electrical connection to body.
I assume it is pretty much a standard size?? for this type led lights.
It is 20-21mm dia x 12-13mm high.
I have checked a couple dozen sites and can find pretty much any part (even little tail cap springs) but not this one.
You can get the modules that come with the spring.
I just need the springs!
Anybody know a source?
Thanks

easy way is try local hardware shops…

thanks. That place is probably a safer bet since they specifically say 20mm.
I need about 30.
They are also way cheaper.

We're glad that you joined, Lethere Belight!

I find that I don't need that spring and often take it off

I’m using them for electrical connection. I have machined aluminum “Modules” that need to be grounded to the case but they are not because of the anodizing.
Springs work great, connect base of module and the base/main body.
(ultrafire 502b hosts)
Still trying to find an easy way to remove the anodizing.
I have used grinding wheel and I see a lot about using oven cleaner but
haven’t tried it yet.
