Anyone know seat mechanism cover screw size. The plastic cover has three screw holes it looks like 3 or maybe 4mm but not sure about pitch.

all i know is that they're VERY tiny...might just want to go to a fastener specialty store (there's two by me called TDE fasteners and screws unlimited) and try some out...

The two of seat mechanism cover screws on both of my seats broke off on mine when I went to reupholster my seats. I used silicon on the inside of the mechanism cover to put them back on and it has worked fine. Those little screws are small and brittle.

Looks like 5-40 not metric at all
