A screw gauge has a smaller pitch than a Vernier caliper, which allows for more precise measurements. The screw gauge also provides a digital reading, which reduces human error in reading measurements. Additionally, the screw gauge has a finer scale that allows for more accurate readings compared to a Vernier caliper.

Vernier caliper has an accuracy of 0.01 cm. But screw gauge has still more. It will be able to give even 0.001 cm. So even third decimal could be got accurately when we use screw gauge instead vernier caliper.
The importance of least count is that it has a capable of taking more accurate and precise measurements
A micrometer , sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw used widely for precise measurement of small distances in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Micrometers are similar in use to vernier calipers but are more precise although the modern digital caliper has blurred the distinction between them.A micrometer is also used to measure the diameter of very small objects that a vernier calliper can't measure for example a screw or a piece of wire.This instrument is mainly used by mechanics.
The conclusion of a screw gauge experiment is typically a statement summarizing the precision and accuracy of the measurements taken using the screw gauge. It may also include any sources of error or uncertainty that were identified during the experiment. Overall, the conclusion highlights the importance of using the screw gauge as a tool for making precise measurements in scientific applications.
The sleeve in a micrometer screw gauge helps to accurately measure small distances by providing a scale with markings that align with the spindle scale for precise readings. This allows for measurements to be taken with high precision and accuracy.
A micrometer screw gauge is necessary for measuring expansion because it provides precise and accurate measurements to determine the small changes in length that occur due to expansion. The micrometer screw gauge has a fine scale and a thimble that allows for consistent and repeatable measurements, making it suitable for measuring small increments of expansion.
The conclusion of a screw gauge or micrometer is the measurement value obtained by reading the scale markings. This value represents the precise diameter or thickness of an object being measured with high accuracy. The conclusion is typically recorded in units such as millimeters or inches.
The range of a laboratory screw gauge is typically around 25-50 mm, although it can vary depending on the specific model. This range allows for precise measurements of small objects with diameters within that range.
Our laboratory screw gauge has a pitch of 1 millimeter.
The sleeve on a micrometer screw gauge is used to provide fine adjustment of the measurement by rotating it to move the spindle in or out slightly. This helps in achieving accurate and precise measurements by allowing the user to make small adjustments without needing to rotate the thimble.
