Proper screw size for ashtray

[BarkSlayer]

I just picked up a genuine Fender chrome ashtray bridge cover for my J-Bass. Can anyone confirm the correct size and length of screws to mount this thing? I'd rather not guess if there's good information out there. Many thanks...

Fender uses pickguard screws on their Custom Shop models that come with the covers mounted, so that's what I used too.
