What are these? - Toyota Yaris Forums

these are two very different screws. the first has a fine thread whereas the second has a course thread and a large head. the one with a large head is most likely for plastic (big head so it doesn't crack the plastic and course threads to grip better) or possible wood. actually, it has to be plastic because it's too short to grip wood and wood screws aren't button heads.

the first one is weird. i'm expecting an open box head or hex head but i don't see it. it's probably used to hold something heavy and with all those threads and the torque that should have gone into tightening it, it couldn't have gotten knocked lose by accident.

i don't think neither belongs to your car so no worries. almost everything in the yaris is made of plastic that snaps together.
