Default Thread size tie-rod 'plug'?

I have a seized tir rod end plug (the threaded end that screws down against the inner spring/ball). I am currently cutting out the plug and want to chase the inner threads before installing a new plug. What is the thread size? It appears to be fine pipe threads but I could be wrong...

Here is an old "thread" on the subject..

https://www.fordbarn.com/forum/showthread.php?t=23581

I don't think they ever got around to answering your question, but these recent pictures show what I measured...that is a SAE 20 pitch gauge....hard to read in the picture.

It is straight thread not pipe.

Assuming you don't have one, The tool of choice would be an enormous screw driver tip that fits a 1/2" ratchet, fits like a glove is by far the best.

There Snap-on sockets in various sizes that they made, and they are called drag link sockets.

The end plug has 60 threads per inch, so measure the major thread diameter to get the rest of the story.

Bob, didn't you mean to say 20 threads per inch? 1955cj5 showed a thread pitch gauge on the nut 20 threads per inch.

I already broke the Bratton's Tie Rod End socket adapter tool. What I got is an end plug that will turn out about 1/4 of a turn and then just dead stops. It HAS to be the threads that are jacked-up. I can turn it back and forth...but, again, no more than 1/4 turn total of travel. I already bent a nice Snap-on screwdriver before I got the Bratton's tool.

There is such a thing as a 1"-20 H4, Plug Chamfer Tap. This has to be what they used back in the day. A tap like that runs nearly $50!!! Let's hope it's not the threads...the attempt to insert a new plug will tell all.

I think you need a 1 1/16x24 tap? Bratton's old catalog said it's 1 1/16 x 24 .

That's what I was kind of getting at... I just like to preserve the original parts if I can...within reason of course...


A local machine shop I called says they'll chase the threads for me for $10 and a Coke.

Ours is 1-1/16 X 20. braol, that would be the way to go. Taps that size are not cheap anyway.

I had one that was stuck so bad it wouldn't turn even after I got the tie rod end white hot. It twisted the tie rod beyond saving.
