I don't know if brass threads are up to the load? The cage is fastened to the standoff by a screw that cannot extend into the frame braze-on so each traditional bottle cage connection becomes a chain of two brass to steel threaded connections.
I'll stick with longer M5 cap bolts and spacer ferrules, like this: http://www.jensonusa.com/Problem-Solvers-Spaceout-Cage-Spacers-Silver-6mm?pt_source=googleads&pt_medium=cpc&pt_campaign=shopping_us&pt_keyword=&gclid=CjwKCAjw-6bWBRBiEiwA_K1ZDeMKTxHCwIIACxmK2viGwNxNBq8316CvVoH3ZIPkwPKp9SvB6v1qrRoCgtoQAvD_BwE Andy Cheatham Pittsburgh On Friday, April 6, 2018 at 10:26:40 PM UTC-4, Benz, Sunnyvale, CA wrote: > > If one really wants to be fancy, one can buy some brass standoffs with M5 > male and female threads.
