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
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 +
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.
