Hi Folks,

I must have lost the paperwork as I can't seem to find any reference to the size of the nut that fits the end of my HSD AT/MT1073-140 4HP spindle anywhere.

I got two nuts with it when I bought it new, but I need more now.

I have bought nuts that purportedly were for ER25 collets (which is what I have and use on it all the time), but they were all too small to fit the threads on the spindle

What brand/model number/type/whatever nut do I need, and where can I buy them from?

Thanks,
Dave Fifield
