Acme Thread Practice Sheet

Using the formulas:

 

P 1/N
Minimum thread Depth .5/N or .5 x P
Maximum Thread Depth .5 x P + .010 or .5/N + .010
Crest Width .3707 x P or .3707/N
Root Width .3707 x P - .0052 or .3707/N - .0052

Find the Pitch, Minimum thread Depth, Maximum thread Depth, Width of the Thread Crest, and the Width of the thread Root.
