Installing a new toilet, it came with these plastic washers, but I've never seen them with any other toilets I've installed, and I'm not really sure what they're for.
The center is slightly conical and is raised by about 1/4". They came in the bag with the other metal parts, and the white plastic covers came in a separate bag.
What are they, and where are they supposed to go?

If not to hold the white cap in place as Robert suggested, I would say they are used to hold the bolts upright while placing the toilet. There would need to be a void under the toliet of course.
