Oil drain plug size

Anyone know which of these I need to get?

I'm seeing multiple sizes, depending on where I look.

Get a strong magnetic drain plug, there are several on Amazon. I used to buy dimple plugs until they were bought out.

Guess I tightened this too much. Didn't seem like it -- just hand tightened as much as I could, then turned it maybe 1/4 - 1/2 turn with a wrench and it snapped. Luckily I was able to get it out with some pliers.

Gonna just stick with the stock drain plug after that.
