Hi peru, I've been looking for some Nimbus parts too... in my case, the Orings dilated to a point where I had to remove them both. There are just no parts out there for it and from what I remember there were no replacement parts in the original order...
For the screws, you might try one out of an electrical chocolate block and see if it fits, I have the feeling that might do the trick...
on review guys says they work on chimbus/nimbus... try finding out if they're replaceable
Screws,SS M2x0.4 HD32 - Kidney Puncher
When you say won't screw down, do you mean the thread is not the same or they are too short/long? FYI IGO-L screws are the same thread size & pitch as the M2 x .4 screws posted above. M2 X .4 is the thread size most RDAs use with different lengths.
Too bad you aren't close to me, I could measure it for you.
The igo-l screw is always lose won't make contact for some reason when screwing it down. Where you located at ?
I just ordered those !! Thanks I hope they work
