What are the measurements in inches.

According to Amazon: inside diameter and V groove width = 4mm = 0.1575 inch, outside diameter = 13mm = 0.5119 inch, groove deepnes = 1.5mm = 0.05905 inch. I use them to guide curtain cord.

I haven't seen any rust as of yet. The device I built that uses them is in my garage so doesn't get direct water on it, but it does get pretty humid.

Do these pulleys come with the pins?

Pins? No pins, just the pulleys.
