A screw gauge has least count of 0.01 mm and there are 50 divisions in its circular scale. The pitch of the screw gauge is :

(A) 0.01 mm (2) 0.25 mm (3) 0.5 mm (4) 1.0 mm

A micrometer screw gauge, is a device which is used measure the dimensions of components more accurately.

In case of micrometer screw gauge the least (L.C.) is given by

\[Least count=\frac{Pitch}{Number of divisions on circular scale}\]

\[Pitch=(Least count)*(Number of divisions on circular scale)\]

\[Pitch=(0.01 mm)*(50)\]

\[Pitch=0.5 mm\]
