I need a part that looks like this: it consists of an "eye"-bolt with a nut and washer which allows this part to be attached to a rod/tube of the right diameter.
These "bolts" are commonly used for attaching bicycle fenders; the picture is from a bike company. However, I want to know if these are available in arbitrary sizes, i.e. multiple combinations of:

From surfing a bit, it seems Baldwin has a variety of handlesets that work with a limited number of their locksets. If you can't buy just the plate, you might only need to buy the lockset.
It seems to be called a 'Landing Plate'
We’ve had two Baldwin handle sets fail on our new front door in the past six months, and I finally figured out why the manfacturer included a second landing plate with the set.
Basically they must have known it would fail prematurely.
The thumb latch is a lever that sits on a set of little pins set on a brass die casting, shown above, which allows it to toggle up and down. Unfortunately, brass die castings are about making things fast, and such parts typically have crappy structural performance and are prone to stress cracking.
What probably happened is that a tiny crack formed on one side of the casting and propagated every time we squeezed up and down on the handle. One side failed (red arrow) and our door handle starting twisting at an odd angle. Thankfully we replaced it with the second landing plate before we were locked out of the house.
After going through two sets, we bought a new set and discovered that designers finally figured out they needed to reinforce the casting for the load by reinforcing the area where the pin sets (right image).
First one is a small pipe inside a large pipe, perhaps with some actual bearings, perhaps not.
Second one is just hinges mounted at the corner of the wooden post.

They appear to be called, fender eyelet bolts, eyelet bolts, or bicycle fender bolts. There is a link I found for Fender Eyelet Bolts, 5mm here.
