To find the divisions on the circular scale of a screw gauge, usually a thimble or sleeve rotates around the fixed frame of the screw gauge. The circular scale on the thimble is divided into equal parts that correspond to the pitch of the screw. By aligning the zero mark on the thimble with the reference line on the frame and counting the number of divisions as the thimble moves, you can determine the measurement.
The least count of a screw gauge is calculated by dividing the pitch of the screw by the number of divisions on the circular scale. The formula is Least Count = Pitch / Number of divisions on the circular scale.
The smallest division on the main scale of the vernier calipers is typically 1 millimeter, while the smallest division on the screw gauge is typically 0.01 millimeters, also known as 0.01 mm.
When the anvil and spindle end are brought in contact, the edge of the circular scale should be at the zero of the sleeve (linear scale) and the zero of the circular scale should be opposite to the datum line of the sleeve. If the zero is not coinciding with the datum line, there will be a positive or negative zero error as shown in figure below.

In a screw gauge, the index line is the reference line on the circular scale that aligns with the main scale to measure the reading accurately. It indicates the value of the measurement being taken by aligning with the closest division on the main scale.
The pitch of a screw gauge refers to the distance traveled by the spindle per revolution. The least count of a screw gauge is calculated using the formula least count = pitch / total number of divisions on the circular scale. It represents the smallest measurement that can be read on the screw gauge.

Pitch is the distance from the crest of one thread to the next. the displacement of the circular scale due to a complete rotation of the screw, along the main scale is called screw pitch..

The thickness of the glass sheet can be calculated using the screw gauge reading, where 1 main scale division corresponds to 0.5 mm and 50 equal circular scale divisions make one complete turn. In this case, the thickness would be (3 \times 0.5 + \frac{8}{50} \times 0.5) mm.
The absolute uncertainty of a screw gauge measurement is typically the smallest division on the scale divided by 2. This value represents the smallest increment in measurement that can be confidently distinguished using the device.

Zero correction in a screw gauge refers to the adjustment needed to compensate for any slight misalignment between the zero mark on the main scale and the zero mark on the circular scale. This correction ensures accurate measurements are taken by aligning the two zero points when no object is being measured.
