Does anyone have close-up pictures of either the Sheldon fender nut or the Daruma options set-up on a bike?
If you look at the end of the existing recessed nut you'll see that it has a 5mm hex opening. So you just use a regular allen key.
No pictures of the Daruma option but it's pretty simple. The big end with the cross hole is where the brake bolt passes through to retain the threaded end with the nut. The washer and rubber is just to aid in centering the whole shebang while avoiding any rattles. And obviously it needs a hole drilled into the fender. And fenders that use this method seem to all have an odd part raised and part recessed spot to allow them to align correctly. At least the two such setups I've worked on did it this way.
