pitch is the linear progress made by the circular scale on the main scale in one complete rotation
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
Depends on the pitch: Fine pitch: m10 * 0.75 pitch , drill diameter = 9.25 mm m10 * 1.0 pitch , drill diameter = 9.00 mm m10 * 1.25pitch , drill diameter = 8.8 mm Coarse pitch (most common use): m10 * 1.5 pitch , drill diameter = 8.5 mm
pitch = 1/Threads per Inch So for a 1/2 - 20 thread the pitch is .1
Screw Pitch is defined as the axial distance between threads. One complete revolution of the screw will move it into an object the distance of the pitch. The smaller the pitch, the greater the mechanical advantage (ability to do work) achieved.

In general in any screw type instrument such as spherometer or screw gauge or micrometer the least count = pitch / no of head scale divisions Spherometer has an advantage of finding the depth in case of curved surfaces.
The distance moved my the screw in one complete rotation in the circular scale is called the pith of spherometer.
The reason a spherometer is called a spherometer is because it measures the radius of a sphere.

abt spherometer
spherometer is an instrument used to measure the curvature of a sphere
A spherometer is an instrument for the precise measurement of the radius of a sphere. The spherometer directly measures a sagittal. Since the spherometer is essentially a type of micrometer, it measures very small things like millimeters.
The difference between screw gauge and spherometer is that spherometer can measure the dimensions of spherical surfaces but screw gauge cannot
because to determine the radius of curvatureof a given spherica surface by spherometer
