  • 1-1/2 x 12 grinder nut

    I am not sure what this nut is used for, I think it holds on a grinder stone. It is 1-1/2 12 LH threads. It uses two 1/4 holes for the spaner wrench.

    Where do I buy one and what should I call it? I can make one but I would rather buy one if possible. I do not have the machine it fits nor do I have access to it.

    Ideas?

    Thanks in advance

    You're unlikely to locate something that is application specific--that is, with holes and everything--but 1-1/2-12 is a standard NF thread so I'd look for an off the shelf jam nut with a LH thread. Drill your own holes and you're done...

      You can find the nuts online, a quick look at McMaster Carr and they had a variety of sizes but not your size.

      You might search for "Toolroom Grinding Wheel Mounting Adapters"

        I doubt it is for a grinder, unless it is a very large one.
        Most all tool room grinders and tool grinders have a 1.25 Diameter thread.
        A 1.5 diameter would not allow the mounting of the most common wheels .

        I am not sure of your question. You "have" a nut and yet you want to buy one like it ?
        If it has no flats, and only holes, it is called a "Spanner Nut"
        Spanner Nuts with fine threads, are made with the face exactly perpendicular to the threads.
        Most likely, it is a nut for a lathe or mill spindle for ball or taper roller bearing adjustment.

          I have a nut the correct diameter and thread pitch. The problem is they want Left hand threads, my sample is right handed. I don't have a clue what machine it goes on. Thanks for the information.

              I see...Thanks !
              Also I should have said the nut face is " perpendicular to the thread axis"
