the pitch is the inverse of the the thread count per inch, or the distance between each thraed
pitch = 1/N
so for a tap of 32 threads per inch pitch is 1/32 = 0.03125 inch

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.
To tap threads effectively and efficiently, follow these steps: Use the correct size tap for the hole. Apply cutting fluid to lubricate and cool the tap. Start the tap straight and turn it slowly to avoid breaking. Use a tap wrench for better control. Back off the tap periodically to clear out chips. Use a thread gauge to check the depth and pitch of the threads. Clean the threads after tapping to remove any debris.
The recommended rod size for the thread die chart is typically determined based on the specific thread size and pitch you are working with. It is important to refer to the thread die chart to find the appropriate rod size for your threading needs.
