Bolt with threads in both directions

Go to the hardware store and look at the turnbuckles. Throw the eye nuts away, and you're left with the bolt you want.

tie rod bolt

Karl if I understand what you are describing, it has 2 threaded rods one lh and one rh. I am looking for one rod with two different threading. Similar to what is in the handles of a cabinet maker's clamp. I guess worst case I just find a cheap one of those and cannibalize it..

Here's real cheap ($3.99 for a 4"):

McMaster-Carr carries them. See p/n 94455A110 for an example. You can pull up the catalog page once you've found that part.

For smaller sizes, nearly fully threaded, many carbide inserts are clamped with such a stud, with a hex socket in one end. Looks like a set screw threaded 1/2 right handed and 1/2 LH.

Thanks Ned, it is certainly much easier to find something when you know what to call it :)

Why not splurge for a couple of dies and make your own? I bet you'll use them again!

Aren't LH dies expensive and hard to come by?

I have yet to cut threads with a die is it tough to do it well? Closest experience was cutting threads in wood with a tap.

You know what, if I remove the turnbuckle, and replace it with a bushing and a little epoxy I have what I need don't I? I need the middle to be non threaded anyway. It needs to be captive in a center block, but spin freely, I was going to do a groove and rollpin thing, but perhaps I could just collar the bushing in.

Amazing what my brain can do if I just get out of its way..

I am glad you elucidated. From the header, I _was_ going to mention knurling

turnbuckles come two ways. One has a circle nut (just gave it a name) with a left hand on one side and a right hand on the other. Then a left hand and right hand eye bolt for each end.

The other style is a bolt with left hand threads on one end and right hand threads on the other. Then a left hand and a right hand eye nut. This is what I thought you were looking for.

There are old ww lathe faceplates (and other tooling, I suppose) double threaded the same way. The LH for outboard placement. Frank Morrison

Hey Absinthe,

This "second" style is very common on sailboats. Used commonly on the shrouds to adjust the mast. Also relatively expensive, and very susceptible to galling if simple lubrication consideration isn't given.

You never did mention threads and sizes.

Take care.

Brian Laws>Karl, I have seen the first kind, but not the second, I will go and peruse

One example, but not really a bolt, can be found on some fishing reels. The kind where there's a "finger" moving back-and-forth to keep the line even across the spool.

Trouble with the Net, there are no "just jokings" any more. There is something, somewhere, that makes a joke not funny cause it's real.

Rockwell-Delta wood turning lathes that were in the school shop I taught in had 6" faceplates LH/RH threaded for use inboard and outboard. Mike in Burns Lake, BC .... we were fortunate it's not Burnt Lake, take time to think of the folks in southern BC and their fight with the fires.
