Oil drain plug size?

[shootme5150]

Just popped my drain plug and the threads are almost completely gone. Threads feel okay in the pan itself, though. Anyone know that diameter and pitch of the bolt? I'm going to grab another one (autozone, hopefully?), but the threads are almost completely gone, so I can't tell what the hell they are. Thanks
