Default When is an M45x3 not a 1.75x8 thread?

There are NO points for Grainger or McMaster.

The 1.75" X 8 tpi are off too much for M45X3 to be a consideration.


Not that far off: 1.75" = 44.45mm; 8 tpi = 3.175mm.


You probably could get the threads to engage, but the load wouldn't be
distributed among the threads. You'd probably have less than a full thread
in actual contact. That's the real weakness in having "almost" the right
thread.
