I'm sure one of the more luthier-esque of this lot will be able to tell me why it is so hard to find small screws, in this case humbucker mounting ring screws (#2 x 9/16" phillips head) and pickguard screws (#3 x 3/8" ).
Yes, I know, order them online... I did. But are they that hard to find locally for anyone else? Home Depot & Lowes don't even come close. Smaller, local, mom & pop type hardware stores all had something
close but not quite, either too long/ too short, slotted vs. phillips, right length/ wrong diameter, etc. (go ahead... get all the ahems out of your system, I'll wait...

)
Are these just older, unpopular sizes? Just curious if anyone knows
