Hello,
I have a job where I need square profile threads on a large nut or inside of a pipe would do. The threads are genuine square and not ASME or Butress.
The max. diameter of the bolt (which I am in possession of) is 26.7mm The min. diameter of th bolt is 24.3mm. The thickness of each 'raised' thread is 0.8mm. The space between each 'raised' thread (ie. the hollow) is 1.1mm. Thread is single start. There is 1 thread per 2mm *(measured over about 8 threads)
*I admit this is not exactly equal to the 'raised' and hollow (1.1 + 0.8) as given above. I am measuring with manual vernier calipers.Can anyone here tell me where I might purchase such a nut or will it it have to be manufactured specially?
My lathe does not have screw cutting ability. Is there any other way to manufacture the threads. I was thinking of using fiberglass resin as a last resort. Large strength is not needed.
Thanks for any input.
Jack
