In general a female thread is cut with a tap. A male thread is cut with a die.
Any time male/female is used to describe something in construction, it refers to which part fits into the other. The male threads into the female part. It is not a type of thread, but how it does it.
Female Pipe Thread.
a helical groove in a cylindrical hole (female thread), formed by a tap or lathe tool, or a helical ridge on a cylindrical bar, rod, shank, etc
It's the depth of the cut from the crest of the surface down to the base on a bolt or screw.
Question is other way round FPT not FTP Female Pipe Thread FPT fittings are equivalent to "National Pipe Thread" (NPT) ones, but different from National Standard Free-Fitting Straight Mechanical Pipe Thread (NPSM) fittings.
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
Female Pipe Thread? FPT = Female Pipe Thread MPT = Male Pipe Thread also seen as FIPT and MIPT (female iron pipe thread and male iron pipe thread).
when a spiral groove is cut over a hole, then it is nut thread. when a spiral groove is cut over a shaft, then it is screw thread.
Pitches of thread shall be cut off.

In crocheting, to end off means to cut the yarn or crochet thread and tie it so that it cannot unravel. What I usually do is cut the thread for enough for at least five knots. Then I do a single stich, pulling the cut thread through the loop that was on the hook. Then I tie at least two knots.
The Fates are the ones who are known for this. Each of them had a distinct role: Clotho (Greek name, her Roman name was Nona) spun the thread of life. Lachesis (Roman name Decima) measured the thread of life allotted to each person. Atropos (Roman name Morta) chose the manner and timing of each person's death. When she cut the thread with shears, someone on Earth died.
