Tri-Fold Tonneau Cover Torx Screws

I searched through many threads on tonneau cover hardware, however, most were in regard to how the cover interfaces with the bed rails. Wondering if anyone has any info or part numbers for the small torx screws pictured below. They hold on some plastic feet. Not entirely sure on the intent of the feet, possibly for storage of the rack off the truck?

Anyway, just curious if anyone has gone through the process of sourcing new screws, or if part numbers exist, before I check all the local hardware stores. Thanks in advance for any leads.
