What are these for? Roti question.

This hardware came in the box with one of my Weber rotis (22"), and I can't figure out what they do or where they go.  No mention of them in the instructions.

Looks like the mounting hardware to attach a rotisserie bracket to a gasser. Mine were stainless tho, still my best guess though.

I never knew either. Still in the bag in the motor box

Looks like bracket mounting screws.
