Type of Screws for front left and right speakers?

[chaps70rt]

I am missing the correct screws for my front left and right dash speaker grills (two per side).   I have the under dash square frames, but need to know the type of scew that fits into these to sandwich between the dash pad.   I am guessing that it is a self tapping black screw with a tapered head to sit flush with the exposed grill?

If anyone knows the type/length or where I can acquire these, that would be great.   I will check RT Specialties in the interim.

Thanks .... Gary

Sorry, don't know the length but this pic should give you some idea

Thanks John .... I picked up something that looks the same from my local NAPA parts store.   They have a variety of #8 screws in black.  They should do the job and look original.
