Professional Screw Gauge FAQ Questions and Answers

Welcome to our comprehensive Trivia Quiz and interview preparation guide. Below you will find a curated list of popular Trivia Questions and Answers specifically for Screw Gauge. Whether you are preparing for a technical interview or just testing your knowledge, these FAQ Questions will help you succeed.

What are the two main parts of the screw gauge?

The two main parts of screw gauge are: a nut and a screw.

What is the least count of the screw gauge?

The least count of the screw gauge is 0.001 cm.

What is a screw?

Screw is a simple machine related to inclined plane.

What is meant by gauge?

The gauge means device or instrument.

What is zero error of the screw gauge?

when the screw tip is in contact with the stud and the zero line of the head scale does not coincide with the reference line of the pitch scale , there is zero error.

Define the pitch?

Pitch is defined as the distance between two nearest threads along the axis of the screw.

How to determine pitch?

Pitch = Main scale reading revealed on rotating circular disc / Number of rotations

When is zero-error positive?

Zero-error is said to be positive when the zero circular scale lies above the reference line only when the fixed and movable studs are in contact.

How back lash error is avoided?

By turning the screw in one direction only.

what is the basic functions of a ratchet?

Ratchet prevents the screw being pressed too hard or too soft against the object.

Why screw guage comes in the category of precision instrument?

The Precision instrument are those instrument that can measure up to a fraction of a mm, e.g., vernier caliper, screw gauge and spherometer.

Why do we take a number of observations for the diameter of a wire?

Even if the wire appears uniform it may not be true. So to take the average value we take a set of readings.

What is meant by range of the screw gauge?

The maximum length of the main scale.

Does the diameter of the screw depend on temperature?

Yes it does. Diameter increases with the increase of temperature and decreases with the decrease of temperature.

What is the Least count? How the L.C. of a screw gauge is found?

Least count is the distance moved by the screw when it is rotated by one circular scale division. It is calculated by using the relation: L.C. = (Pitch of the screw / No. of circular scale divisions).

The pitch of a screw is 1 mm and the number of divisions on the head scale is 100. What is the least

Least count = pitch/ No: of divisions on the head scale = 1/100 = 0.01 mm

What is the degree of accuracy of the screw gauge?

Degree of accuracy = L.C. or Reading power = 0.001 cm.
