In general a female thread is cut with a tap. A male thread is cut with a die.
pitch = 1/Threads per Inch So for a 1/2 - 20 thread the pitch is .1

It depends which thread the screw is, the pitch and depth of the thread varies.B.S.F. - 5.3 mmWhitworth - 5.10 mmB.S.P. - 11.80 mmU.N.F. - 5.50 mmU.N.C. - 5.2 mmA.N.C., A.N.F. and B.A. threads are numbered, I.S.O threads are in metric
when lead of the screw is equal to the pitch it is called single threaded screw
thread pitch, they even make guages for these, there always included in a tap and die set but you could likely find one at a hardware or automotive store
A tap is a tool, a tap can cut or clean the threads of a bolt hole, there are differant diameters and thread pitch, a dye is the opposite of a tap it cuts or cleans the threads of a bolt.
As far as i can tell the thread is the same as on a Schrader valve which is: * Metric: 7.7 mm OD, thread root diameter is 6.9 mm x 0.794 mm pitch. * English: 0.305 in OD, thread root diameter 0.302 in x 32 tpi (threads per inch) Now where do we find the tap for it?
In general a female thread is cut with a tap. A male thread is cut with a die.
Cutting a thread on a shaft
On a bolt, you can sometimes clean out the thread with a knife or hacksaw blade enough to start the nut and tighten it to reform the thread past the damage. In a hole, they make thread chasers that will recut the the thread. You can just run a tap in the hole and it will usually find the old grooves.
pitch = 1/Threads per Inch So for a 1/2 - 20 thread the pitch is .1
A pitch of three means three threads per inch so, one thread every .333 inches.

A thread guide is a tool to measure the number and pitch of threads on a bolt
It depends which thread the screw is, the pitch and depth of the thread varies.B.S.F. - 5.3 mmWhitworth - 5.10 mmB.S.P. - 11.80 mmU.N.F. - 5.50 mmU.N.C. - 5.2 mmA.N.C., A.N.F. and B.A. threads are numbered, I.S.O threads are in metric
A thread chaser is used to clean and restore damaged or dirty threads vs. a tap or, die which cuts threads.
