My father owns a fordson super major and lost his oil drain plug on him. What size of drain plug does it take? Is it standard or metric? The hole measures approx. 5/8 inch.

SOURCE: 5200th of an inch is equal to what metric? 5600th

.0395 = 1mm

1.1 mm x.0395=.043 That is about what a Ford Spark plug is set at.

.052 gap divided x .0395=1.3mm

You will have to remove the oil pan & silver
braze on a nut inside, the size of the drain plug, if
you want a permanent fix

There is nothing there to tap out

SOURCE: Socket Size?

That looks the same as on FWD GM cars, and they are 36 mm.
Use a metric ruler and measure from side to side-that will tell you.

It should be a 13mm but you probably find that someone has worked on it in the past with worn tools. If the head is worn then I would suggest getting a new drain plug and replace it when you do the oil change. To get it loose you may succeed with a single hex 13mm socket. Failing that you may have to chisel it loose. A bit brutal but some mechanics don't adhere to torque settings and over tighten these simple items!
