What kind of screws are used for the door knob of an interior door

doorknob

When my painter took off the door knob of an interior door, he lost the two screws that held the door knob in place. Does anyone happen to know what kind of screws they are? They look like some type of Philips-head machine screws.

Thanks for all of the answers. After bringing the door knob to Home Depot, I ended up buying #8-32 x 1" brass round-head machine screws, which worked perfectly.
