First calibrate the micrometer by dialing the spindle to zero and adjusting the anvil until it is flush against the spindle. Measure the screw until the ratchet begins to click and take the first reading. This reading can then be compared to a machining book to verify the pitch diameter.
when lead of the screw is equal to the pitch it is called single threaded screw
acme thread
6 is the diameter of the bolt whereas 32 is the thread pattern. Usually used in machine screws.
The larger thread spacing has 2 disadvantages: It is not a strong since it has less effective area; and if you are using to precisely locate something there is less precison per turn.
This is a tool that is used to measure the pitch diameter of a screw. This tool looks like a standard micrometer except that the anvils are specially configured to reach into the screw thread groove and touch the pitch diameter of the screw thread. The screw thread micrometer does not measure any other aspect of the screw thread. It does not measure the: pitch; threads-per-inch; major diameter; minor diameter; flank angles; lead; helix angle.

Oh, dude, the effective diameter of a screw thread is basically the imaginary diameter that represents the size of the thread where the width of the thread and the depth of the thread are equal. It's like the Goldilocks of diameters, not too big, not too small, just right for threading stuff together. So, yeah, that's the effective diameter for ya.
It refers to the diameter of the screw. More precisely, it is a 0.138" diameter screw. You can get it in with various head style and thread pitch.
what does a standard thread gauge measure
well, if you want to measure the length, just stretch the tape and measure it. If you want to measure the diameter, measure the circumference of the screw, then divided by 3.1415, then you will get the diameter.
to cheak the diameter of something
the minor diameter should be between 4.917mm and 5.153 mm, so the largest allowable size is 5.153mm
The proper thread notation for a 14mm diameter screw with a 1.5mm pitch and 40mm length would be M14x1.5x40.

The angle of a thread of a screw is an angle between the threads and it is the defining factor for the shape of the screw thread.
