What size is M24X2 Castle Nut?

[Tim in New York]

The Woods finish mower I bought this spring has a healthy gearbox leak that I am trying to get to the seal to replace. Once I got the gearbox off the mower I found a bit pulley that drives anything held on with a big castle nut. In SAE it was between 1 and 1/4 and 1 and 1/2 sockets. Parts diagram says its M24 x 2. None of my metric sockets are big enough, or my 12" cresent wrench. So I order a M24 socket. Got here overnight on Amazon Prime, but its too small by a lot.

So what the heck size of a socket do I need?

Thanks!

Says 36mm.

McMaster has the best search feature by far and is great as a reference, not just for buy parts. They have CAD prints for nearly everything available as well.

Thanks! I found the same info somewhere else. Guess I am back to Amazon for a 36MM socket.

A local parts store may have one, that size was used on some automobile front axle shaft nuts.

M24X2 refers to the thread. 24mm thread diameter by 2mm thread pitch.

1 inch is 25.4 MM so it would be between a 32 to 38 mm. the M24 x 2 is thread size not socket size.

36mm is 1.417 inches 20 thousandths smaller than 1 and 7/16 inches, if you have a 6 point socket you can probably get by using it.

36M socket should be here on Monday. By the time I am done I may have an expensive set of metric sockets, one at a time.

A $10 micrometer would save time and money

If you have a nearby Harbor Freight they will have a 33 mm socket.

Yeah, but you'll have to buy the whole set. HF no longer sells individual wrenches.

I usually buy big sockets at my nearby Ace Hardware, which carries Craft$man. For a cheaper tool, Home Depot sells individual sockets but I don't know that they carry the really large sizes.

Just as a 1/2 inch wrench doesn't fit a 1/2 inch bolt head, a 24 mm wrench won't fit an M24 nut.

Tape measure would be close enough.

Didn't know that...bought a 30mm deep well impact socket from them about a month ago.

You probably mean vernier calipers... I like the kind with the dial. That way you don't have to remember how to read them.

Micrometers only measure in 1" increments so you'd need a set, and they cost a lot more than $10.

But, a tape measure would be perfectly fine for this job. When Harbor Freight was giving them away all the time I'd grab one each time I went by a store. Got about a dozen cheap 25ft tape measures scattered around the farm. Still can't find a single one of them when I need it...

Incorrect. I was in there on Sunday and they still sell individual sockets. They just don't sell ALL the individual sockets. Only the more common sizes.

Auto parts stores should have a loaner axle nut set.
