Drain plug 3/8 +/-

[jaxs]

I reccomend you take a look at this thread //www.tractorbynet.com/forums/threads/rounded-off-drain-plug.393632/
and if you don't find what you are looking for come back here and we can see if anyone has ideas not already mentioned.

You didn't say what this is. 3/8" pipe size or head size? Possible that it is a 10 MM or 7/16" ? Evac it through the dipstick or drain via the filter are other possibilities.

Slightly larger than 3/8" is 10mm. (0.393" to be exact). 7/16" = 0.438"

I think he is trying to use the 1/2" (square) drive end, not the actual socket end.
I've done this before with square heads plugs, nuts.

Correct. It is a square 3/8 head and I am using the drive end of an extension not a socket.

Yes, I've done same with a socket where you can find the right 3/8 drive 12 point socket that will fit on a 3/8 drive ratchet.
The socket is less likely to round out than the plug.

Trying to recall where I have seen plugs with recessed square heads? Conduit plugs?

They make sockets for plugs- Of course, I found this after chewing one into oblivion so now I have a set.

If I did not already have a complete set of 8 point sockets, I might consider something like this:

https://www.lowes.com/pd/Gator-Grip...ric-3-8-in-Drive-6-point-Socket-Set/999949198

Don't know why they refer to it as 6 point as the description indicates it will work with all shapes as long as there is a flat.

 

[Root Cause]

I have a lot of tools but it just never occurred to me that I really needed one until I had one really seized up. I went to Lowes and nothing. Seemed odd that I never ran across them before but sure enough, I found a set and bought them. I paid a hefty price to replace that d*&^ vent tube coming out of an Onan generator. It was something I didn't know existed much less to open it and clean out the soot periodically.

They make a socket specifically for 3/8 and 1/2 inch square plugs. Just have to search for them.

Napa 10mm 4 point socket for $8. Maybe get one on ebay or amazon?
