help with ID of trim fastener
 

cross-posted in Exterior Forum:

here's one to stump the experts: I need to identify (part number or at least a model and application) a 10mm diameter x 10mm length black wafer-head trim screw (picture attached). the fellow who gave it to me swears it's a Lexus part (and he's an experiencedbody guy, so I believe him), but the local parts counter has no clue. I'd really appreciate the help. thanks.
