Has anyone tried Brass cartridge mounting screws?

@bdp24 wrote I’m with @best-groove: brass is too soft.

Are you having an issue with the brass threads stripping or do you not like the sound of brass bolts?

Crepes!
how much torque do you guys use?
this isn’t NASCAR.
Which is to say I’ve used brass, titanium, stainless, or plastic screws and never stripped or galled any of them.

I use brass bolts in my neck.  My bride thinks they look nice. 

I'm not sure how hard your screws need to be in this application. I'm thinking resonance is the only issue other than magnetism. In that regard. Does anyone know where I can get plastic cartridge screws?

Mounting screws should be aluminum or titanium for best sound.
