A screw pitch gauge is a precision instrument. It is used for measuring diameter of circular objects mostly wires, with an accuracy of 0.001cm. It consists of a hollow cylinder mounted on a U frame. The hollow cylinder leads to a ratchet which is meant for fine adjustment. The U frame consists of a flat end known as stud and a screw on the other side. This screw can be moved inside the nut by fitted in the U frame by rotating the hollow cylinder called the thimble. This is called the main scale. The hollow cylinder or the thimble is graduated into 50 or 100 equal parts. This is called the circular scale

Why is screw gauge commonly called as micrometer screw gauge?
A micrometer screw gauge is commonly known as a micrometer. This is a form of calipers used for measuring small dimensions. Screw gauge in extensively used in the engineering field for obtaining precision measurements. The article describes the principle and main parts of a basic micrometer screw gauge.

What would happen if the micrometer screw gauge was not reset back from the end of the bar?
In an Experiment to determine the linear expansion of copper, a micrometer screw gauge is one of the apparatus used, and it's usually fixed at the end of the metal rod. Now the reason why the micrometer screw gauge should always be reset back from the end of the bar is to avoid the heating of the micrometer screw gauge which would expand it,hence giving inaccurate measurements when taking the change in length of the rod. Since the experiment is all about linear expansion,it involves heat also. This heat is the one that would heat the rod and after the heat would be uniformly conducted throughout the bar,it would also heat the micrometer screw gauge at the end. This is the reason why it should be reset back from the end of the rod(to avoid it's heating)
