On my old Farmall tractor I have square nuts on the drawbar attachments. The "bolts: that these are on, are not just bolts, but some special swivel device similar to an eye bolt. These square nuts are rather large and need a 1-1/4" open end wrench. The problem is that these nuts are right next to the transmission and there is no room to swing an open end wrench. The only way I can get these nuts off, is with a socket. But even looking at antique tools at auctions, I have never seen a socket for square nuts? Normally, if it's just a regular bolt, I'll just use my angle grinder and grind the nut off, but this is not an option here. Has anyone ever seen sockets for square nuts, and know a source to buy them? If they are available, I'm sure the socket would be cheaper than having to replace those special bolts. (Once I get them off, they will be replaced with hex nuts).

I have a set of Crescent sockets that are square and hex...they look like an internal spline. But I don't know if they make larger sizes?

Hi, a double hex socket will fit, making contact on 4, of the 12 points in the socket. Just need the right sized socket.

DON"T use a 12 point if it is at all tight. 8 point sockets are made and readilly available for EXACTLY that application. I've split 12 pointers trying that stunt.

Right, no "meat" there.

He's going to replace it anyway. Pipe wrench may be the perfect tool.
