When lathe cutting threads how do you measure external screw threads to know they have been cut deep enough?
The only sure method is to have the appropriate internal (female) thread eg. a nut available and to try this on the cut thread. If the fit is too tight then another cut or pass must be made on the lathe. If you are cutting both male and female threads to match then cut the female thread first and use it to check the cutting of the male thread. Submitted by Bill Lavery
What are the tools in threading?
Taps and dies are used in threading. To make an internal thread, you drill a hole smaller than the thread width, then slowly screw a 'tap' into it cutting a thread very slowly. -For an external thread, you choose a rod or bolt larger than the final thread, then screw a hard, threaded disc down onto it.

How do you measure major diameter of internal thread?
The major diameter is the diameter of the crest of the thread. Use a Vernier gage and mesure the diameter of the crest points of contact ( maximum external thread diameter). Unified National thread series defines the expected major diamter and tolerance. For internal threads ( nuts) the major diameter is the diameter of the roots of the thread.
